  • Patent number: 11077837
    Abstract: A hydraulic brake system for a vehicle which has expanded functionality, where a pre-charge occurs in the brake system upon deactivation of the cruise control, reducing the time needed to generate pressure in each brake unit, reducing stopping distance. The pre-charge function involves generating pressure in each caliper of the brake system upon deactivation of the cruise control function of the vehicle, such that the hydraulic brake system is pre-charged prior to the driver of the vehicle applying force to the brake pedal, which reduces stopping distance. One aspect of the pre-charge function includes generating enough pressure such that the brake pads contact each corresponding rotor. Another aspect of the pre-charge function includes generating enough pressure such that the brake pads apply force to each corresponding rotor, providing a minimum amount of deceleration prior to the driver of the vehicle applying force to the brake pedal.

    Abstract: A method of obtaining data relating to the timing of a transition between phases of a traffic control signal. The method involves obtaining live probe data relating to the travel of vehicles in the region of the traffic control signal, and using the data to determine times at which a given transition of the signal has occurred. This is carried out by consideration of the distance from the traffic signal at which a vehicle waits when stopped at the signal, and a time of passing the signal, as determined using the probe data. Different transition time pairs are analyzed to obtain time differences between the transition times. A cycle time which best fits the time difference data is determined, and used with the transition time data to predict future transition times of the traffic control signal.

  • Patent number: 9589463
    Abstract: A method of obtaining data relating to the timing of a transition between phases of a traffic control signal. The method involves obtaining live probe data relating to the travel of vehicles in the region of the traffic control signal, and using the data to determine times at which a given transition of the signal has occurred. This is carried out by consideration of the distance from the traffic signal at which a vehicle waits when stopped at the signal, and a time of passing the signal, as determined using the probe data. Different transition time pairs are analyzed to obtain time differences between the transition times. A cycle time which best fits the time difference data is determined, and used with the transition time data to predict future transition times of the traffic control signal.

  • Patent number: 9546606
    Abstract: A throttle body assembly includes a housing defining a throttle bore with a throttle plate in the bore and mounted on a shaft. An electric motor has a pinion gear. A gear assembly includes an intermediate gear and a sector gear and transfers rotational drive from the electric motor to the throttle plate. Biasing structure biases the sector gear and thus the shaft to cause the throttle plate to close the throttle bore defining a closed position thereof. When the motor is energized, rotation of the pinion gear causes rotation of the gear assembly, against the bias on the sector gear, thereby causing rotation of the shaft to move the throttle plate from the closed position to an open position. A position sensor assembly determines a position of the plate.

  • Patent number: 9341125
    Abstract: When an accelerator operation amount is 0, a throttle actuator is controlled by means of isochronous control by using a second throttle operation amount (?tps2) for the isochronous control, and, on the other hand, when the accelerator operation amount is not 0, the throttle actuator is controlled by means of droop control by using a first throttle operation amount (?tps1) for the droop control. When an engine rotation speed is equal to or lower than a LOW rotation speed, larger one of the first and second throttle operation amounts (?tps1 and ?tps2) is used, and when the engine rotation speed is equal to or higher than a HIGH rotation speed, smaller one of the first and second throttle operation amounts (?tps1 and ?tps2) is used, to thereby control the throttle actuator by means of the isochronous control.

  • Patent number: 9005082
    Abstract: An ECU increases an engine rotation speed when the ECU determines that an inclination angle of an uphill is larger than or equal to a predetermined value, an accelerator is off and a vehicle speed in a direction opposite to a travelling direction of a vehicle, indicated by a specified range, is increasing. Subsequently, the ECU acquires an engine stall predicted vehicle speed, and calculates a predetermined value used in an immediate engine stall determination condition from a current rate of increase per unit time of a turbine rotation speed. Then, the ECU determines that immediate engine stall determination is affirmative when a rotation speed difference between the engine rotation speed and the turbine rotation speed becomes smaller than the predetermined value, and executes engine stall prevention control.

  • Patent number: 9008928
    Abstract: Disclosed is a vehicle control apparatus which can prevent the deterioration of drivability. The ECU can set a control accelerator opening degree to be converted when a control permission condition is established. The control accelerator opening degree is equal to or larger than an accelerator lower limit which is larger than an idle determination value for determining an automatic stopping of an engine by an eco-run. The control accelerator opening degree thus set can prevent the drivability from being deteriorated without the automatic stopping of the engine being caused even if the accelerator opening degree is converted to reduce the torque of the engine with the establishment of the control permission condition.

  • Patent number: 9002619
    Abstract: It is possible to suppress fluctuations of an air intake amount when the open degree of an air intake control valve is unknown. An engine includes an impulse valve common to all the cylinders arranged in the engine. The impulse valve is arranged in a communicating tube provided at the downstream side of a serge tank. An ECU executes impulse valve drive control. In the control, the ECU judges whether a rotation angle sensor which detects the open degree of the impulse valve has failed. If it is judged that the rotation angle sensor has failed, the ECU controls a drive motor and a drive circuit for driving a valve body so that a valve body of the impulse valve rotates inside the communicating tube. Here, the rotor of the drive motor which defines the rotation speed of the valve body has an rpm which is set in accordance with the mechanical rpm NE of the engine.

  • Patent number: 8843297
    Abstract: Provided is an rpm control device for a general-purpose engine, which is capable of realizing droop control in a spark-ignition engine only by the adaptation of isochronous control. When the droop control is selected, a rotation decrease rate (K) (value equal to or smaller than 1) is obtained from an engine rpm and a load. The result of multiplication of a basic target rpm (Nb) requested by a driver by the rotation decrease rate (K) is obtained as a target rpm (No). By setting the rotation decrease rate to a smaller value as the load becomes higher, the target rpm (No) is set smaller than the basic target rpm (Nb). The isochronous control is performed by using an electronic throttle so as to achieve the obtained target rpm (No) to realize the droop control in a pseudo-manner.

  • Patent number: 8807117
    Abstract: In a situation where a conventional inductive throttle sensor is used with a motor-driven throttle valve device to detect the rotation angle of a throttle shaft, plural sensor connection conductor sections for connecting a connector terminal to a circuit board terminal section are formed on the cover on one lateral surface side of a circuit board in the long-axis direction. This increases the dimension of the cover in the short-axis direction (the dimension in the direction of air flow in an intake path). Consequently, it is difficult to install the motor-driven throttle valve device and inductive throttle sensor in a narrow engine room. This problem is addressed by using a separate member to achieve electrical conduction between a stator circuit board and a conductor routed inside the cover installed over the stator circuit board in a concentrated manner on one side of the circuit board.
