Claim Text:
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; 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; receiving, from a camera on the vehicle, a continuous video stream into buffer storage; receiving, from a sensor on the vehicle, a signal to transfer the continuous video stream from the buffer storage to a memory, wherein receiving from the sensor on the vehicle a signal to transfer the continuous video stream comprises receiving a signal that the regenerative braking system has been automatically activated; receiving, from a system controller on the vehicle, a first predefined time, the first predefined time indicating a time prior to the receiving of the signal to transfer in which to initiate a transfer of the continuous video stream from the buffer storage to the memory; receiving, from the system controller on the vehicle, a second predefined time, the second predefined time indicating a time after the receiving of the signal to transfer in which to stop the transfer of the continuous video stream from the buffer storage to the memory; and saving the continuous video stream in the memory.
