Abstract: A microprocessor of an on-vehicle electronic control unit controls an on-vehicle current consumer group responsive to input signals of on-vehicle sensor groups based on control program, fixed control constant and semi-fixed control constant respectively stored in first block of a no-volatile memory, and variable control constant having been transferred from second block of the no-volatile memory to RAM memory; and content of RAM memory is learned and compensated during operation. When power supply switch is OFF, contents of the RAM memory are sequentially added to and written in the second block. When the second block is filled up to capacity, batch clear is executed and, thereafter, the latest data is written. Thus, a flash memory divided into the first and second blocks capable of executing batch clear separately is employed as a non-volatile memory, enabling to perform save processing many times with small number of times of batch clear.

Abstract: In a vehicle steering apparatus, front wheels are controlled to be turned by a computer program processing. A displacement/torque conversion section 51 converts a steering angle ? into a steering torque Td that is in relation of exponential function. A torque/lateral-acceleration conversion section 52, torque/yaw-rate conversion section 53 and torque/curvature conversion section 54 convert into an anticipated lateral acceleration Gd, anticipated yaw rate ?d and anticipated turning curvature ?d based upon the steering torque Td. Turning angle conversion sections 55, 56 and 57 calculate target turning angles ?g, ?? and ??. A turning angle deciding section 58 decides a target turning angle ?d among the target turning angles ?g, ?? and ?? according to the detected vehicle speed V. A turning control section 60 controls the steered wheels to be turned into the target turning angle ?d.

Abstract: An automatic steering control performs an automatic parking control which automatically steers steerable wheels of a vehicle, without requiring a driver to perform steering wheel operation, such that the actual steering angle of the steerable wheels follows a changing target steering angle, whereby the vehicle is moved to a target parking state. When the actual steering angle fails to follow the target steering angle because of insufficiency of the steering drive force of a steering actuator, a braking force difference imparting control is performed so as to apply a predetermined braking force on the steerable wheel located inside a target vehicle locus. As a result, a steering moment is generated in the steerable wheels. This steering moment serves as a force for compensating for the insufficiency of the steering drive force of the steering actuator. As a result, the actual steering angle accurately follows the target steering angle.

Abstract: The present invention allows an existing single-sequentialized navigation main unit to be virtually multi-sequentialized with simple structure. An intervention device 3 receives from a front monitor 4 and a rear monitor 5 acquisition requests which request various kinds of screens from a navigation main unit 2. In response to the acquisition requests, the intervention device 3 performs a mediating process or an adjusting process for various kinds of screens which are received from the navigation main unit 2 and are scheduled to be output to the front monitor 4 and the rear monitor 5. Therefore, even if the intervention device 3 receives a plurality of acquisition requests from the front monitor 4 and the rear monitor 5, the intervention device 3 can sequentially send the acquisition requests one by one to the navigation main unit 2. Accordingly, this allows the navigation main unit 2 to be virtually multi-sequentialized.

The controller (16) performs a countermeasure in response to the collision type. The controller (16) may include a collision location estimator (22) for determining collision severity and collision contact location on the vehicle (12) and a coordinated device activation system (24) for performing the countermeasure.

Abstract: A novel vehicle deceleration control device for ensuring a proper distance between a vehicle and a preceding vehicle, etc., equipped on a vehicle, automatically decelerates the vehicle by controlling braking force based on a target deceleration, calculated based on a relative distance and a relative speed between the vehicle and its preceding vehicle, etc., when automatic deceleration is required. The inventive device, however, will decelerate the own vehicle based on a maximum allowable deceleration when the magnitude of the target deceleration is larger than the magnitude of the maximum allowable deceleration, restricting the vehicle deceleration. The maximum allowable deceleration is determined based on the vehicle speed of the own vehicle when a predetermined condition is satisfied, and maintained at a constant or within a predetermined range, thereby enabling a driver to judge the necessity of braking operation by himself during restricting the vehicle deceleration more easily than ever.
