SENSOR-TRIGGERING OF FRICTION AND REGENERATIVE BRAKING

摘要

In an emergency stop situation, the regenerative braking system is used to assist in rapid deceleration, by combining regenerative braking with conventional friction brakes. Sensors can also be used to trigger the braking systems, even before the driver is able to react. These sensors might include external cameras, ABS activation detection, radar and ultrasound.

主权项

1. A method for automatically activating simultaneously a friction braking system and a regenerative braking system of a vehicle, the method comprising the steps of:
detecting a position and a movement of one or more objects in surroundings of a vehicle; detecting an operation of a brake pedal of the vehicle; calculating a risk of collision of the vehicle with the one or more objects based upon the position and the movement of the one or more objects, the calculated risk of collision representing a probability that a collision of the vehicle with the one or more objects is unavoidable without an immediate intervention of the friction braking system and the regenerative braking system; and in response to the brake pedal being operated with an operating speed exceeding a predetermined operating speed, or the calculated risk of collision exceeding a predetermined risk of collision, automatically activating simultaneously the friction braking system and the regenerative braking system of the vehicle.
