VEHICLE WITH AUXILIARY POWER UNIT AND CONTROL METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To realize a safety regenerative braking without requiring the troublesome operation of a lever or the like because the determination of a regenerative braking quantity in proportion to the operation quantity of the lever or the like or the operation of the regenerative braking quantity so as to make the actual vehicle speed follow a desired vehicle speed, which is so far performed as a regenerative braking method for a vehicle with electric power unit often, causes an extremely dangerous sudden braking in the vehicle on a down slope. SOLUTION: This method comprises a process S1 for detecting the manual drive force of a vehicle traveling part; a process S3 for detecting the speed of the vehicle traveling part; a process S4 for detecting the acceleration thereof; a process S5 for calculating the traveling resistance of the vehicle traveling part from the detected manual drive force, speed and acceleration; and a process of imparting the regenerative braking force to an auxiliary power drive part when the calculated traveling resistance is a negative value.
