Patent number: 8712644Abstract: A vehicle control apparatus including a braking force applying device of a hydraulic type, capable of applying a braking force to each of a plurality of wheels. A hydraulic pressure controlling device controls a hydraulic pressure of the braking force applying device such that each of the wheels is not locked. A hydraulic pressure increasing or decreasing period changing device changes an increasing or decreasing period of the hydraulic pressure controlled by the hydraulic pressure controlling device. A controlling device controls the hydraulic pressure increasing or decreasing period changing device to change the increasing or decreasing period of the hydraulic pressure corresponding to each of the wheels in contact with a road surface having a high road surface friction coefficient, from that where a left-right braking force difference is not generated, to where the left-right braking force difference is generated by the hydraulic pressure controlling device.Type: GrantFiled: January 19, 2011Date of Patent: April 29, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yoshitaka Fujita, Mitsutaka Tanimoto, Go Inoue

Publication number: 20140039763Abstract: Lane keeping control is ended in accurate timing which does not give an uncomfortable feeling to a driver. In a vehicle 10 which is provided with a steering mechanism 200, an EPS actuator 300, and a VGRS actuator 500 and which can change a rudder angle regardless of a driver's steering input due to the cooperative control of the aforementioned mechanism and actuators, an ECU 100 performs LKA end control. In the control, in cases where a winker lever 16 is operated in a period of performing LKA control for making the vehicle 10 follow a target driving route, if the indicated direction of the winker lever 16 is different from a generation direction of generating an assist steering torque TA of the EPS actuator 300 in the LKA control, the LKA control is promptly ended. In cases where the indicated direction is equal to the generation direction, if a steering angle MAdrv corresponding to the driver's steering input exceeds a steering angle MAlka generated by the LKA control, the LKA control is ended.Type: ApplicationFiled: October 9, 2013Publication date: February 6, 2014Applicant: Toyota Jidosha Kabushiki KaishaInventors: Yoshitaka FUJITA, Takahiro KOJO
