Problems solved by technology

[0004] However, when the vehicle causes uniflow and the integrated value of the steering torque exceeds the threshold value, the uniflow corresponding control starts, so there is a problem that it takes time until the uniflow corresponding control is started after the vehicle causes uniflow.

Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described based on the drawings. In this embodiment, a case where the vehicle control device of the present invention is applied to a vehicle control system of a vehicle will be described as an example.

[0032] figure 1 It is a block diagram of a vehicle control system 1000 including a vehicle control device 100 according to an embodiment of the present invention. The vehicle control system of this embodiment includes a steering unit 1 , a steering wheel 2 , wheels 3 and 4 , and a vehicle control device 100 . The vehicle control device 100 of the present embodiment controls the steering of the wheels 3 and 4 in accordance with the operation of the steering wheel 2 .

[0033] The steering unit 1 has a shaft 11, a motor 12, a steering angle sensor 13, a torque sensor 14, and gears (not shown). The shaft 11 is connected to the left and right drive wheels. A rack & pinion type steering gear is used as the gear, ...

Abstract

The present invention is a vehicle control method for controlling a vehicle using a vehicle control device equipped with a sensor and a control device that detects the external state of the host vehicle, wherein a steering amount in the lateral direction relative to the driving lane of the host vehicle is given to make the host vehicle The control of returning the driving trajectory to the target trajectory is performed as normal control. Using the detection data of the sensor, it is determined whether other vehicles are driving in the adjacent lane adjacent to the driving lane of the own vehicle. In the case of running, the responsiveness of the steering amount is made higher than the responsiveness of the steering amount during normal control before the host vehicle passes other vehicles.

Description

technical field [0001] The invention relates to a vehicle control method and a vehicle control device. Background technique [0002] There is known a steering device for a vehicle, which is equipped with a motor for steering, and when the vehicle is in a straight-ahead state, based on vehicle information including a steering torque and a steering angle, the driving power of the motor is controlled, thereby giving the steering system Control of assist torque (for example, refer to Patent Document 1). The steering device for a vehicle described in Patent Document 1 calculates the torque integration value of the cumulative steering torque, and when the torque integration value is equal to or greater than a threshold value, performs single-flow handling of the driving power of the motor so as to eliminate the single-flow phenomenon of the vehicle. control. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2015-37932 [0004] However, when the vehicle causes uniflow an...
