Remote stop system for a vehicle
A remote stop system for a vehicle configured to be operated autonomously or semi-autonomously. The remote stop system includes a mechanical remote stop system configured to apply a first braking force and an electrical remote stop system configured to apply a second braking force. A remote stop actuator is configured to send a wireless control signal to the vehicle. The remote stop actuator having two states: a first state having the remote stop actuator transmitting the wireless control signal to the mechanical remote stop system and the electrical remote stop system and a second state having the remote stop actuator without transmitting the wireless control signal to the mechanical remote stop system and the electrical remote stop system. In the second state, the first braking force and the second braking force are applied simultaneously. A vehicle system includes the vehicle and the remote stop system.
