[0027] A parking assist control system equipped with a vehicle travel control device to which a first embodiment of the present invention is applied will now be described with reference to the drawings.
[0028] figure 1 is a diagram showing the overall configuration of the parking assist control system of this embodiment. In this figure, a vehicle VL has a front left wheel, a front right wheel, a rear left wheel and a right rear wheel, and their corresponding structural components are designated and indicated by FL, FR, RL and RR, respectively.
[0029] The parking assist control system of the present embodiment has a configuration including a brake control ECU 1; a hydraulic brake device 2; an electric parking brake (hereinafter referred to as "PKB") 3; each wheel 4FL, 4FR, 4RL , 4RR, each wheel is equipped with wheel cylinders (hereinafter referred to as "W / C") 41FL, 41FR, 41RL, 41RR; vehicle wheel speed sensors 5FL, 5FR, 5RL, 5RR; vehicle-mounted LAN bus 6; engine control...

[0114] A second embodiment of the present invention will be described. In the first embodiment described above, the braking force is adjusted in order to disturb the balance between the braking force and the driving force generated in the vehicle VL, which in turn causes the vehicle VL to move only a set distance. However, in the second embodiment, the driving force is adjusted in order to achieve the same operation and effect as the first embodiment. Note that the difference in this embodiment is only that processing is performed by the parking assist control ECU 8 . The parking assist control system is the same as that in the first embodiment, therefore, only different parts will be described.
[0115] Also, in the present embodiment, upon receiving a request to perform parking assist control, the parking assist control ECU 8 calculates the final target parking position and a motion trajectory toward the target parking position, and executes parking assist control. However...
