Embodiment Construction

[0012] Below, according to Figure 1 to Figure 4 One embodiment of a travel control device for a vehicle will be described.

[0013] exist figure 1 3 schematically shows a vehicle including travel control device 70 according to the present embodiment. The vehicle includes a front wheel steering angle adjusting device 10 for adjusting the steering angle θF of the plurality of front wheels FL, FR, a steering device 20 connected to each of the front wheels FL, FR, and a steering angle θR for adjusting the plurality of rear wheels RL, RR. rear wheel steering angle adjustment device 30. The steering angle θF of the front wheels FL, FR is referred to as "front wheel steering angle θF", and the steering angle θR of rear wheels RL, RR is referred to as "rear wheel steering angle θR". In addition, the vehicle includes a braking device 40 that adjusts the braking force of the vehicle, and a drive device 50 that adjusts the driving force of the vehicle.

[0014] The front wheel steer...

Abstract

A travel control device 70 of a vehicle provided by the present invention is provided with a turning control unit 72 that executes a turning assist control for causing a turning state amount to follow a target turning state amount by causing at least one of a front wheel steering angle adjustment device 10, a rear wheel steering angle adjustment device 30 and a brake device 40 to be driven; and a steering instruction unit 73 that, when steering is not being performed during the turning assist control, instructs a steering device 20 to derive holding torque and apply the holding torque to a steering wheel 21. In the turning assist control when steering is not being performed, the turning control unit 72 causes at least one of the rear wheel steering angle adjustment device 30 and the brake device 40 to be driven, but causes the front wheel steering angle adjustment device 10 not to be driven. In the turning assist control when steering is being performed, the turning control unit 72 causes the front wheel steering angle adjustment device 10 to be driven.

Description

technical field [0001] The present invention relates to a travel control device for a vehicle. Background technique [0002] Patent Document 1 describes an example of a travel control device that executes turning assist control that assists turning of a vehicle traveling on a travel lane. In this travel control device, when the vehicle is turned without the driver steering, the vehicle is turned by automatically adjusting the steering angle of the front wheels connected to the steering device. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2012-6506 [0004] When the vehicle is automatically turned by the execution of the turning assist control described above, it is considered to keep the steering angle of the steering wheel at a neutral point. The so-called neutral point refers to the steering angle when the steering angle of the front wheels is "0 (zero)". In the case of maintaining the steering angle at the neutral point, a torque for maintaining the steeri...
