Vehicle steering auxiliary reminder device and method

Abstract

The invention provides a vehicle steering auxiliary reminder device and method and belongs to the technical field of automobile driving assistance. The vehicle steering auxiliary reminder device and method solve the problem that steering auxiliary reminders are not effective in making steering prompts in the prior art. The vehicle steering auxiliary reminder device comprises a vehicle navigation main engine and an electric power-assisted steering controller, wherein the electric power-assisted steering controller is connected with the vehicle navigation main engine; a power-assisted motor is connected with the output terminal of the electric power-assisted steering controller; the electric power-assisted steering controller determines the direction in which a vehicle needs to turn according to a received turning and lane-changing signal and outputs a control signal to the power-assisted motor; and the electric power-assisted steering controller controls the power-assisted motor to output the steering force in the same direction that the vehicle needs to turn to a steering mechanism. The method comprises the following steps: (1) ensuring the start of a steering auxiliary reminder; (2) determining the direction in which the vehicle needs to turn through the steering auxiliary reminder; (3) assisting in reminding a driver to make a turn; (4) quitting the steering auxiliary reminder. The vehicle steering auxiliary reminder device and method is convenient and effective to remind the driver to make a turn and change a lane.

Description

technical field [0001] The invention belongs to the technical field of automobile auxiliary driving, and relates to a vehicle steering auxiliary reminding device and method. Background technique [0002] With the advancement of technology, there are more and more functions on the car, such as electric power steering function, car navigation function and so on. The steering wheel of the vehicle is connected to the steering shaft, and the steering wheel drives the steering shaft to rotate to complete the steering of the vehicle. After the electric power assist system is added, the electric power steering controller judges the steering wheel steering and the magnitude of the torque, and then the electric power steering controller controls the output steering of the power assist motor. The assist torque is given to the steering shaft, wherein the assist motor is connected to the steering shaft through a reduction mechanism. Car navigation is a commonly used and very convenient ...

Problems solved by technology

[0005] Although the device can improve the effect of vehicle steering prompts, all modules in the device need to be installed on the steering wheel protective cover, and the steering wheel protective cover is installed on the steering wheel. First, it affects the appearance. Second, the steering wheel is often operated. Both the vibration prompting module and the Bluetooth module are easily damaged, so that the prompting effect cannot be achieved. The most important thing is that the vibration prompting module can only be felt when the driver touches it, so the steering prompting effect is not very effective, even if the driver holds the Vibration prompt module, long-term operation will also damage the vibration prompt module, so the device is neither convenient nor effective for steering prompts
