VEHICLE AUTOMATIC DRIVING CONTROL APPARATUS

摘要

A vehicle automatic driving control apparatus executes an automatic traveling control by performing setting on preset automatic-driving-required drive torque as target torque, and includes a traction-control-required drive torque setting unit that sets, when a preset operating condition of a traction control is satisfied, traction-control-required drive torque as the target torque to decrease drive torque and thereby suppress a drive wheel slip, an automatic-driving-required drive torque decreasing unit that gradually decreases, based on a preset amount, the automatic-driving-required drive torque when the traction control is operated, a torque comparing unit that compares the traction-control-required drive torque with the decreased automatic-driving-required drive torque, and an automatic-driving-required drive torque setting unit that completes the traction control and performs the setting again on the decreased automatic-driving-required drive torque as the automatic-driving-required drive torque for the automatic driving control, when the traction-control-required drive torque is determined as exceeding the decreased automatic-driving-required drive torque.

1. A vehicle automatic driving control apparatus that obtains traveling environment information and traveling information of an own vehicle, and executes an automatic traveling control by performing setting on preset automatic-driving-required drive torque as target torque, the automatic-driving-required drive torque being drive torque required for automatic driving, the vehicle automatic driving control apparatus comprising:
a traction-control-required drive torque setting unit that sets, when a preset operating condition of a traction control is satisfied, traction-control-required drive torque as the target torque to decrease drive torque of the own vehicle and thereby suppress a slip of a drive wheel of the own vehicle, the traction-control-required drive torque being drive torque required for the traction control; an automatic-driving-required drive torque decreasing unit that gradually decreases, based on a preset decreasing amount, the automatic-driving-required drive torque when the traction control is operated; a torque comparing unit that compares the traction-control-required drive torque set by the traction-control-required drive torque setting unit with the automatic-driving-required drive torque decreased by the automatic-driving-required drive torque decreasing unit; and an automatic-driving-required drive torque setting unit that completes the traction control and performs the setting again on the decreased automatic-driving-required drive torque as the automatic-driving-required drive torque for the automatic driving control, when the traction-control-required drive torque is determined by the torque comparing unit as exceeding the decreased automatic-driving-required drive torque.
