A parking-lot-leaving support apparatus, to execute parking-lot-leaving support to support a vehicle leaving a parking lot, based on a positional relationship between the vehicle and an obstacle in a back-and-forth direction of the vehicle, includes a determination unit configured to determine whether an obstacle exists in a side direction of the vehicle, based on a detection result of a detection unit that detects an obstacle in the side direction of the vehicle; and an inhibition unit configured to, when the determination unit has determined that the obstacle exists in the side direction of the vehicle, inhibit the parking-lot-leaving support in a direction that coincides with the side direction.

Parking-lot-leaving support apparatus and vehicle

A parking assist system includes an electronic control unit configured to: estimate first extending directions of obstacles respectively located on right and left sides of a target parking space in a state where a host vehicle moves across in front of the target parking space; calculate a planned moving path based on the estimated first extending directions; as the host vehicle is guided into the target parking space, estimate second extending directions of the obstacles respectively located on the right and left sides of the target parking space while updating the second extending directions; determine whether the estimated and updated second extending directions satisfy a predetermined condition; and when the updated second extending directions satisfy the predetermined condition, update the planned moving path by using the updated second extending directions instead of the first extending directions or the second extending directions before being updated.

This automatic clutch control device selects a normal mode when a road friction coefficient is not less than 0.3 at a disconnecting operation starting point (time t), selects a little low-speed mode when it is not less than 0.1 but less than 0.3 and selects a low-speed mode when it is less than 0.1. Further, when a vehicle stabilizing control such as a traction control or the like is not executed at the time t, this device selects the normal mode, while when a vehicle stabilizing control is executed at the time t, it selects the low-speed mode. Moreover, this device selects a high-speed mode when the vehicle is in a sports running mode at the time t, while selects the normal mode when the vehicle is not in the sports running mode. A connecting operation of a clutch is performed with a speed corresponding to the selected mode in an automatic clutch connecting/disconnecting control by a clutch connecting/disconnecting actuator upon executing a gear-shift control.

Automatic clutch control device

The automatic clutch control device controls, regardless of the gear-shift operation, the clutch to be brought into a half-clutch state or to a perfect disconnecting state according to a running state of a vehicle from the following five viewpoints deceleration slip amount of driving wheels RL and RR; a convergence time of a driving wheel speed to the driving wheel in a pressure-down mode during a vehicle stabilizing control (for example, ABS control); a continuation time of a judder vibration; whether the vehicle is in a spinning state or not; and whether there is a possibility that an engine stall occurs during a traction control. As a result, this device can attain at least one or more objects of the improvement in stability of the vehicle, improvement in precision of the vehicle stabilizing control, improvement of comfortableness of the occupant and prevention of the occurrence of the engine stall.
