ABSTRACT:
A method for preventing the slipping of a vehicle engine during braking, by judging whether or not there is an excessive slipping of driven wheels on the basis of detection values detected by driven wheel speed detectors for detecting driven wheel speeds and detection values detected by follower wheel speed detectors for detecting follower wheel speeds, such that if it is decided that there is excessive slipping during engine braking, an actuator capable of changing the output from an engine mounted in the vehicle is operated to increase the output from the engine, wherein the method comprises steps of: detecting a gear position in a transmission disposed between the engine and driven wheels; determining a target engine revolution number on the basis of the gear position and the detection values of the follower wheel speeds at the time when it is decided that there is the excessive slipping; and determining a control amount for operation of the actuator on the basis of the target engine revolution number. Thus, it is possible to provide improvements in responsiveness and accuracy of the control conducted when excessive slipping is produced during engine braking.
