Abstract
An apparatus for kinesthetic signaling to a driver of a motor vehicle is described. The apparatus signaling the driver if, in the context of a system for controlling vehicle speed, a deliberate shutdown or one occasioned by a malfunction is imminent or exists; or if, in the context of a system for controlling vehicle speed, a preset maximum deceleration value is not sufficient to prevent a collision between the motor vehicle and a preceding vehicle or an obstacle. The apparatus includes a device that modulates a braking setpoint, or a variable derived from it, in such a way that the motor vehicle experiences a temporally fluctuating deceleration that is perceptible by the driver.
Claims13
An apparatus for kinesthetic signaling to the driver of a motor vehicle comprising:
- a modulator modulating one of a braking setpoint and a variable derived from the braking setpoint so that the motor vehicle experiences a temporally fluctuating deceleration that is perceptible by the driver if one of:
- a deliberate shutdown is one of imminent and present,
- a shutdown occasioned by a malfunction is one of imminent and present, and
- a preset maximum deceleration value is not sufficient to prevent a collision between the motor vehicle and one of a preceding vehicle and an obstacle.
