摘要： A motor vehicle output power control system effects a slip control process for preventing the drive wheels of a motor vehicle from slipping against unstable maneuverability and a trace control process for preventing the motor vehicle from failing to make a turn due to an excessive lateral acceleration. The motor vehicle output power control system has a torque control unit for reducing the drive torque produced by the engine irrespective of controlling action of the driver. A target speed for the drive wheels is established on the basis of the motor vehicle speed, and a reference drive torque for the engine is set depending on the target speed for the drive wheels. Based on a slip of the drive wheels, a target drive torque for the engine is established. The torque control unit is controlled by an electronic controller so that the drive torque produced by the engine is equalized to the target drive torque. The reference drive torque is corrected on the basis of the slip of the drive wheels, thus calculating the target drive torque. The drive torque of the engine can be quickly lowered in order not to unduly exceed maximum frictional forces between the road surface and the drive wheels. The motor vehicle is controlled by the motor vehicle output power control system to run safely with improved control responses because of a reduced number of corrective factors for control.

摘要： A control apparatus for controlling the output of a vehicle equipped with an internal combustion engine. The control apparatus includes a torque control unit and an electronic control unit, is electrically connected to various sensors for detecting the running conditions of the vehicle, and is capable of controlling, e.g., the operations of a throttle valve and an ignition plug, to thereby control the driving torque of the engine. The control apparatus calculates a reference driving torque of the engine on the basis of the vehicle speed, and also calculates a slippage of the driving wheels on the basis of a deviation of peripheral speed between the driving and driven wheels. A correction torque for the reference driving torque, which is calculated by the control apparatus on the basis of the detected slippage, is subjected to restriction in accordance with the vehicle running conditions, and the reference driving torque is corrected in accordance with the restricted correction torque, to obtain a target driving torque. Thus, the control apparatus controls the operations of the throttle valve and ignition plug such that the actual driving torque of the engine coincides with the target driving torque.

摘要： A motor vehicle output power control system quickly reduces the drive torque produced by an engine on a motor vehicle depending on the magnitude of a lateral acceleration which is produced when the motor vehicle makes a turn, or the amount by which drive wheels slips when the motor vehicle is accelerated. A target drive torque depending on the lateral acceleration and a demanded drive torque demanded by the driver of the motor vehicle are added at a predetermined ratio into a turn target drive torque, which is selected as a final target drive torque. The motor vehicle output power control system includes an electronic control unit for controlling an actuator to lower the output drive torque of the engine, independent from controlling action of the driver, such that the output drive torque of the engine is equalized to the final target drive torque.

摘要： A method and apparatus for learning the neutral position of vehicle steering angle, in which first neutral position decision means decides that the steering shaft is at a neutral position when a running speed detector detects that the vehicle speed is not less than a predetermined threshold level, that the difference in peripheral speed between the right and left drive wheels is smaller than a predetermined first straight-running threshold value and also when a steering shaft reference position sensor continues to detect a reference position of the steering shaft for at least a first count time. The vehicle steering angle is computed on the basis of the angular displacement from the neutral position thus learned.

摘要： A cruise control device is provided with a vehicle speed sensor for detecting the actual vehicle speed, and an electronic controller for controlling the opening of the throttle valve based on the detected vehicle speed, to bring the vehicle speed close to a target vehicle speed. The electronic controller serves to obtain a vehicle speed deviation between the target vehicle speed set by a set switch and the actual vehicle speed, select one of a P control mode, a P/D control mode and a fuzzy control mode corresponding to the magnitude of the vehicle speed deviation, and control the opening of the throttle valve. In addition to these functions, the electronic controller may additionally have the function of estimating a change in the vehicle speed provided that the current opening of the throttle valve is maintained, to obtain a correction value for the vehicle speed so that a corrected vehicle speed corrected by the correction value is used to control the opening of the throttle valve. Further, in the case of a vehicle provided with an automatic transmission, a shift diagram applied to a cruise control mode may be prepared in addition to the shift diagram for the automatic transmission itself, so that the electronic controller may have the function of effecting a shifting of the gear ratios of the automatic transmission.
