Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018144576
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle control device capable of accurately and promptly interposing slip suppression control, in the vehicle control device for controlling a vehicle drive device.SOLUTION: A vehicle control device 3 controls a vehicle drive device 4. The vehicle control device 3 includes a speed calculation section 7a, a speed estimation section, a motion feedback calculation section 7b, and slip estimation means 9. The vehicle calculation section 7a calculates speed in a predetermined direction of a vehicle on the basis of feature amount. The speed estimation section estimates speed in the predetermined direction on the basis of speed or acceleration detected by motion detection means 2. The motion feedback calculation section 7b makes a feedback calculation adding to the feature amount, a value obtained by interposing a proportional gain in a deviation between calculation speed calculated by the speed calculation section and the estimation speed estimated by the speed estimation section. The slip estimation means 9 compares the calculation speed with the estimation speed, and estimates that the vehicle is in a slip state in the predetermined direction when the estimation speed exceeds the calculation speed.SELECTED DRAWING: Figure 1
