摘要： Rear wheels are controlled based on rear-wheel slip angle (.beta.r). A desired rear-wheel steering angle (.delta.r) is expressed as .delta.r=-G(S)kr.beta.r, where G(S) is a derivative transfer function and kr is a steering coefficient. The desired rear-wheel steering angle is applied to a rear-wheel steering control system for controlling the rear wheels to the desired rear-wheel steering angle.

摘要： In an automatic brake system provided with a pressure source including both an oil pump and an accumulator, one or more brake systems are controlled on the basis of pump pressure smoothly at low speed, but on the basis of accumulator pressure at medium or high speed. Since the pump pressure and the accumulator pressure can be used properly according to vehicle speed, the vehicle can be braked automatically and appropriately in case of the presence of a collision against another vehicle running ahead.

摘要： A preceding vehicle, an inter-vehicle distance between a self vehicle and the preceding vehicle, vehicle speeds of the self vehicle and the preceding vehicle, an operation of a cruise control, a braking operation, a brake pressure and the like are detected and inputted to a cruise control unit. Based on these input signals, the cruise control system selects a constant speed running mode when the inter-vehicle distance is larger than a specified value and selects a following-behind running mode when the inter-vehicle distance is smaller than the specified value. When the constant speed mode is selected, the vehicle travels at a constant preset vehicle speed by operating a throttle actuator and a brake actuator. Further, when the following-behind running mode is selected, the vehicle travels keeping the inter-vehicle distance at a specified distance by the operation of the throttle actuator and the brake actuator. If the following-behind running mode lasts longer than a specified time, the preset vehicle speed is updated into a vehicle speed higher than an average vehicle speed within the specified time. Further, when a braking operation is detected during the following-behind running mode, if the brake pressure is lower than a specified value and the vehicle speed is higher than a predetermined lower limit vehicle speed, the cruise control is restored when the braking operation finishes.

摘要翻译： 前车，自车和前车之间的车间距离，自车和前车的车速，巡航控制的动作，制动操作，制动压力等被检测并输入 到巡航控制单元。 基于这些输入信号，当车辆间距离大于指定值时，巡航控制系统选择恒速运行模式，并且当车辆间距离小于指定值时选择跟随运行模式。 当选择恒速模式时，通过操作节气门执行器和制动器致动器，车辆以恒定的预设车速行驶。 此外，当选择后跟行驶模式时，车辆通过节气门执行器和制动器致动器的操作使车辆间距离保持在指定距离。 如果后续运行模式持续时间超过指定时间，则预设车速在指定时间内更新为高于平均车速的车速。 此外，当在后续运行模式下检测到制动操作时，如果制动压力低于规定值并且车速高于预定的下限车辆速度，则当制动操作完成时，恢复巡航控制 。
