[0023] Referring to the drawings, description will be given of a parking assist control system to be installed in a vehicle in which a first embodiment of the present invention is implemented.

[0024] figure 1 is a schematic diagram showing the entire structure of the parking assist control system according to the first embodiment of the present invention. exist figure 1 , components corresponding to the left front wheel, right front wheel, left rear wheel, and right rear wheel of the vehicle VL are denoted by FL, FR, RL, and RR, respectively.

[0025] The parking assist control system in the first embodiment includes: brake control unit ECU 1; hydraulic brake equipment 2; electronic parking brake unit 3 (abbreviated as PKB hereafter); Wheel cylinder (hereafter referred to as W / C) 41FL, 41FR, 41RL and 41RR (see figure 2 ); wheel speed sensors 5FL, 5FR, 5RL, and 5RR; vehicle LAN bus 6; engine control ECU 7; parking assist control ECU 8; warning indication and alarm generat...

Abstract

Initial value theta 0 of a vehicle deflection angle L and an initial value L0 of a distance L are set, a normalized coefficient R is determined from the ratio of the vehicle deflection angle theta or the distance L to the initial value theta 0 or the initial value L0 when vehicle stop control is started, and the target speed VREF of a body speed VL is determined by that coefficient R. Since the body speed V of the vehicle VL is very low when the vehicle VL arrives at a target parking position, the vehicle VL can be stopped precisely at the target parking position.

Description

technical field [0001] The present invention relates to a parking assist control device and a parking assist control system for parking a vehicle at a desired position with high accuracy through a vehicle stop control operation during a parking assist control operation. Background technique [0002] A parking assist control device, such as the one disclosed in Japanese Unexamined Patent Application Publication No. 2003-11760, can control the parking assist control operation so that the driver can efficiently park the vehicle at a desired position when intending to stop. Such a parking assist control device is configured to generate a braking force by automatic braking at the time of parking. [0003] However, for example, the above patent documents only describe that the vehicle stopping operation activated by the parking assist control device is realized by automatic braking, and do not describe any specific method for highly accurately parking the vehicle at a desired posi...
