摘要： A slip value of a driving wheel is calculated on the basis of driving and driven wheel velocities detected by wheel velocity sensors. A target engine output of a vehicle is set in accordance with the slip value of the driving wheel. A target fuel amount to the engine is set in accordance with the target engine output. A target opening of a throttle valve is set based on the target fuel amount. An opening correction value of the throttle valve is calculated in accordance with a deviation between the target fuel amount and an actual fuel amount to the engine detected by a fuel controller. A traction controller controls to cause the engine output to coincide with the target engine output by ontrolling the opening of the throttle valve to attain an opening as a sum of the target opening and the opening correction value.

摘要： A parameter representing a real generation amount is detected and the intake is increased based on the detected parameter instead of on-information of the switch of the electric load. Therefor, the rotation speed in idling is stabilized without excess idle-up. The controllability is excellent due to the combination with controlling the load of the alternator itself.

摘要： Described herein is a drive-by-wire vehicle engine output control system. The system permits good-response acceleration by a driver's simple and reasonable operation, i.e., by operating an accelerator pedal and also a prompt response even when a sudden load change occurs. Further, the system permits precise speed control by simple equipment even when the deviation of a vehicle speed from a target vehicle speed is large. Output changes of an engine can be controlled within a permissible output change range by (a) comparing a target autocruise engine output with an acceleration demanding ending output, choosing the larger engine output and then controlling the engine to give the larger engine output, (b) controlling the engine to achieve a target autocruise engine output obtained from a speed correction torque and a running load torque or (c) limiting an engine control quantity on the basis of a permissible output change value.

摘要： An air-fuel ratio control apparatus capable of preventing production of a torque shock which is liable to be caused in an engine when the air-fuel ratio is varied for a change between rich combustion and lean combustion. When the engine is in any other operating state than a specific operating state, an electronic control unit of the apparatus subjects a valve, which is disposed in a first bypass line for bypassing a throttle valve to on/off-duty control in accordance with the difference between a target suction air amount necessary for control for a lean air-fuel ration, computed according to a throttle valve opening detected by a throttle sensor, and a suction air amount detected by an airflow sensor, and urges a bypass valve for opening a negative-pressure responsive valve in a second bypass line. As a result, a predetermined amount of air is allowed to be supplied to the engine through the throttle valve and the first and second bypass lines. In the specific operating state, enough air supply through the throttle valve for control for a rich air-fuel ratio is allowed while preventing air supply through the bypass lines.
