Warning device for vehicle

摘要

In a warning device for a vehicle, a basic target current value setting unit sets a basic target current value based on a steering torque and a vehicle speed. When a lane deviation determining unit determines that there is a high possibility that a vehicle will deviate from a lane, a warning vibration wave generator generates a warning vibration wave containing a plurality of frequency components. A target current value is computed by adding the warning vibration wave to the basic target current value. A motor current to be applied to an electric motor is controlled so as to approach the target current value.

主权项

1. A warning device for a vehicle comprising:
a vibration wave generator that generates a warning vibration wave based on an operating state of a vehicle; and a vibration applying device that applies warning vibration to a steering member based on the warning vibration wave generated by the vibration wave generator, the warning vibration wave containing a plurality of frequency components, wherein the vibration applying device applies the warning vibration wave in such a way whereby the frequency component having a higher frequency has a larger amplitude.
