<p><P>PROBLEM TO BE SOLVED: To lessen an operation burden by assisting a driver with a brake operation. <P>SOLUTION: The vehicle deceleration control unit includes an engine brake which decelerates a vehicle by putting a vehicle drive source in a state driven from a passive side, and when a driver maintains a brake operation amount, the deceleration resulting from the engine brake is increased at a rise-up rate Rr. Then, once a predetermined time interval has elapsed after a period of increasing the deceleration at the rise-up rate Rr, the deceleration is increased from the deceleration at that time at a build-up rate Rb less than the rise-up rate Rr. When the driver increases or decreases the operation amount of the brake, i.e., does not maintain the brake operation amount, the deceleration resulting from the engine brake is maintained. The deceleration by the engine brake is limited to an upper limit value G<SB POS="POST">LlM</SB>or less. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
