Driving support device

A driving support device executes a limit control to control a vehicle in such a manner that an actual acceleration of when the vehicle is being reversed does not exceed a limit acceleration during a time period from a time point that a start condition becomes satisfied to a time point that an end condition becomes satisfied. The driving support device sets a state of itself to either one of a prohibiting state in which an execution of the limit control is prohibited or an allowing state in which the execution of the limit control is allowed. The driving support device sets the state of itself to the allowing state when a failure that the driving support device cannot detect/receive a request signal occurs.

CLUTCH DEVICE AND COLLISION MITIGATION MECHANISM
20220073061 · 2022-03-10 ·

When a collision occurs, a driving force of a drive shaft is transmitted to a reversing high-load multiple disk clutch via an inertia absorbing gear mechanism. Then, the driving force is transmitted to a gear via a gear, and inertia is absorbed and the driving force acts to rotate an output shaft at a low speed. On the other hand, when the gear rotates, a regenerative/backing up motor also rotates, and so-called regenerative driving is also performed. Due to these operations, the output shaft rapidly decreases in rotation speed, and goes into a rotation stopping state from a forward rotating state. Then, when a vehicle speed sensor detects that the vehicle speed has reached “0,” the regenerative/backing up motor is driven, the output shaft is driven to rotate reversely for several seconds, and thereafter, driving of the regenerative/backing up motor is stopped.

A controller as a control apparatus for a hybrid vehicle determines whether or not to perform switching from a first traveling mode in which a hybrid vehicle is caused to travel using torque of a motor without using torque of an engine to a second traveling mode in which the hybrid vehicle is caused to travel using at least the torque of the engine. The controller, when determining that switching is to be performed from the first traveling mode to the second traveling mode, performs control to reduce output torque of the motor by a predetermined amount. After this control, the controller shifts a first clutch from a released state to an engaged state so that the torque of the motor is transmitted to the engine via the first clutch, and cranks the engine using the motor to start the engine.
