Title:
TRAVEL CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/011348
Kind Code:
A1
Abstract:
Using the disclosed travel control device, it is possible to cancel vehicle speed control without subjecting the driver to discomfort when there has been a pedal operation of a brake pedal by the driver during vehicle speed control. When there has been a pedal operation of the brake pedal (112) by the driver during control that decelerates the vehicle by means of a vehicle speed control means, the driver brake fluid pressure (Pd) generated by a master cylinder (111) by means of the pedal operation and the actuator brake fluid pressure (Pa) generated by a brake actuator (121) on the basis of the deceleration-amount command value (A) of a vehicle speed control unit (131) are compared, and the output of the deceleration-amount command value (A) from the vehicle speed control unit (131) is sustained until the driver brake fluid pressure (Pd) exceeds the actuator brake fluid pressure (Pa).
