Disclosed is a hill start assist for a vehicle capable of suppressing vehicle movement contrary to driver's expectations and capable of improving driving feel even if the magnitude of detected values regarding the driving direction of driving wheels or that of driving force of the driving wheels are abnormal. Specifically disclosed is a hill start assist (1) for a vehicle comprising an ECU (20) that includes a detection state determining unit (25) that determines the detection state of a shift lever position switch (14) and a retention control unit (26) that performs retention control in which a reduction in braking force of a braking device (5) is suppressed when the operation of a brake pedal (2) is stopped. The retention control unit (26) further includes a first retention control performing unit (27) selected when determination results of the detection state determining unit (25) are normal and a second retention control performing unit (29) selected when the determination results of the detection state determining unit (25) are abnormal. The second retention control performing unit (29) performs the retention control in a manner such that the vehicle is retained in a stop state for a second stop retention time (T2) shorter than a first stop retention time (T1) set by the first retention control performing unit (27).
摘要:
A vehicle motion control apparatus suppresses strangeness feeling in a driver when a signal from a sensor which detects an operated state quantity of a vehicle and a motional state quantity thereof is abnormal. The vehicle motion control apparatus includes a control unit, and sensors. An actual-state-quantity obtaining unit outputs a vehicle-body actual slip angle and an actual yaw rate to a deviation calculating unit. A reference dynamic-characteristic model calculating unit calculates a vehicle-body reference slip angle and a reference yaw rate using a dynamic-characteristic model and outputs those to the deviation calculating unit. A virtual external-force calculating unit feeds back a virtual external force to the reference dynamic-characteristic model calculating unit based on a deviation output by the deviation calculating unit. At this time, a virtual-external-force-calculation controlling unit controls correction of a virtual external force based on a signal indicating a detection condition output by the sensors.
