Abstract: Upon occurrence of a change in the load versus fluid loss property, the braking force for the given brake pedal operation amount is changed so that the vehicle operator is enabled to perceive the change in the load versus fluid loss property. In a vehicle brake system comprising a motor actuated cylinder, wheel cylinders, a stroke sensor for detecting a brake pedal operation amount, a target value setting circuit for setting a target stoke of the motor actuated cylinder, and a fluid pressure compensating circuit for correcting the target stoke upon detection of a deviation between a brake fluid pressure reference value corresponding to the brake pedal operation amount and an actual brake fluid pressure in a direction to reduce the deviation, a stroke limiting circuit restricts a compensation value produced by the fluid pressure compensation circuit according to the brake pedal operation amount.

Abstract: If the temperature (Tig) of a switching element (25) in a source power supply circuit (24) of an electric motor (2) increases to be equal to or greater than a first predetermined value (?) while an electric vehicle (1) is in a stall state, a torque command for the electric motor (2) is reduced while a braking force command for a brake unit (10) is increased, and if the temperature (Tig) of the switching element (25) subsequently decreases to be equal to or less than a second predetermined value (?(<?)), the braking force command for the brake unit (10) is decreased while the torque command for the electric motor (2) is increased. The increment rate of the torque command for the electric motor (2) is varied in accordance with the degree of road gradient.

Abstract: In a brake-by-wire vehicle brake system using a feedback control unit (12a, 12b, 31, 36, 45) for producing a brake fluid pressure according to a brake input, a response restricting unit (26, 39, 48) restricts a response property of the feedback control unit when an extraneous brake fluid control operation is detected. Thereby, the control unit is prevented from excessively reacting to changes in the brake fluid pressure caused by the extraneous brake fluid control operation, and the vehicle brake system can provide a highly responsive property and a resistance to changes in the brake fluid pressure at the same time.

Abstract: In a vehicle capable of performing regenerative braking and fluid pressure braking, in changing from the regenerative braking to the fluid pressure braking in response to a decrease of a vehicle speed due to braking, a fluid pressure braking force is increased from 0 at a first increasing rate when the vehicle speed falls to or below a first threshold value (V1), and the fluid pressure braking force is increased at a second increasing rate, which is higher than the first increasing rate, when the vehicle speed falls to or below a second threshold value (V2), which is smaller than the first threshold value (V1). With this configuration, while occurrence of a squeal noise of a wheel cylinder can be prevented by setting the first increasing rate of the fluid pressure braking force at a small value, a required braking force can be generated without any problem by setting the second increasing rate, to be used subsequently thereto, of the fluid pressure braking force at a large value.

Abstract: At a time (t3) when a vehicle speed is decreased below a switching-start vehicle speed and the switching from regenerative braking to fluid pressure braking is performed, even if a slave cylinder is caused to be operated by driving an electric motor at the same time of starting the reduction of regenerative braking force, the increase of fluid pressure braking force is delayed by an ineffective stroke in the slave cylinder. Accordingly, a temporary drop of total braking force of the regenerative braking force and fluid pressure braking force is generated. However, at a time (t2) when a vehicle speed is decreased below a switching-preparation-start vehicle speed, the electric motor is, beforehand, caused to drive slightly to cancel out the ineffective stroke in the slave cylinder. This can prevent a temporary drop of the total braking force of the regenerative braking force and fluid pressure braking force at the time of the switching, and can thereby prevent deterioration of brake feeling.

Abstract: A program parallelizing apparatus, a program parallelizing method and a program parallelizing program capable of creating a parallelized program of better parallel execution performance at a high speed. A fork point determination section extracts all fork points in a sequential processing program, and removes fork points with a static boost value satisfying a static rounding condition. A fork point combination determination section obtains a dynamic boost value and an exclusive fork set for each fork point that appears when the sequential processing program is executed with input data, and removes fork points with a dynamic boost value satisfying a dynamic rounding condition. As a maximum weight independent set problem, the fork point combination determination section obtains an initial combination of fork points, which are not in an exclusive relationship, with the maximum sum of dynamic boost values, and retrieves an optimal combination based on an iterative improvement method.

Abstract: A brake system includes an electric brake force generator which brakes a wheel using a driving force of an electric motor and an electric motor controller that performs a field-weakening control of the electric motor. The electric motor controller performs the field-weakening control of the electric motor which then operates the electric brake force generator. Thus, the rotational speed of the electric motor is increased when the field weakening control is performed by the electric motor controller thereby quickly activating the electric braking force generator to enhance response of brake force generation.

Abstract: With a single program divided into a plurality of threads A to C, at the execution of the threads in parallel to each other by a plurality of processors, determination is made of a forkability of a slave thread into other processor in response to a fork instruction in a master thread being executed by a predetermined processor and when forkable, the slave thread is forked into other processor and when not forkable, the fork instruction is invalidated to execute an instruction subsequent to the fork instruction by the predetermined processor and then execute a group of instructions of the slave thread by the predetermined processor.

Abstract: A BBW type brake system which operates fluid pressure generators having electric motors as drive sources based on an electrical signal to brake a wheel, field weakening control of the electric motors is performed in the initial stage of operation of the fluid pressure generators to increase the rotational speed of the electric motors. Therefore, it is possible to reduce a time lag before the braking force actually generates after the electrical signal for operating the fluid pressure generators is outputted, thereby improving operational responsiveness. After the braking force actually generates, the field weakening control is cancelled to secure a required braking force with a sufficient torque.

Abstract: In a multi-thread executing method of dividing a single program into a plurality of threads and executing the program by a plurality of processors in parallel, at a time of every fork instruction of the executing thread, when there already exists a child thread generated form the above thread, the program cancels the child thread or makes invalid all the fork instructions other than the first fork instruction having succeeded in forking the child thread, hence to select one fork instruction for creating an effective child thread from a plurality of fork instructions existing within a parent thread, during the execution of the parent thread. Therefore, it can assure the Fork-Once limitation at a time of the program execution.

Abstract: Each processor comprises a register for storing start address of a forked child thread and a comparator for detecting that the value of its own program counter is coincident with the start address stored in this register. Each processor sends a thread stop notice to a thread controller when the value of its own program counter is coincident with the start address of the forked child thread and ends the execution of a parent thread when receiving a thread end permission from the thread controller.

Abstract: In a parallel processor system for executing a plurality of threads in parallel to each other by a plurality of thread execution units, the respective thread execution units allow for forking of a slave thread from an individual thread execution unit into another arbitrary thread execution unit. The respective thread execution units are managed in three states, a free state where fork is possible, a busy state where a thread is being executed, and a term state where a thread being terminated and yet to be settled exists. At the time of forking of a new thread, when there exists no thread execution unit at the free state, a thread that the thread execution unit at the term state has is merged into its immediately succeeding slave thread to bring the thread execution unit in question to the free state and conduct forking of a new thread.
