description An automotive vehicle has an electric parking brake (EPB) and an electronic control unit (ECU) configured to control the EPB. The ECU is configured to control the EPB to apply it upon determining that a driver is not present in the vehicle. The ECU is configured to determine whether the driver is present in the vehicle or not based at least upon there having been or not having been a steering input. The ECU is configured to determine that there has been a steering input when a steering torque signal from an electric power steering system of the vehicle has changed by at least a threshold amount during a set period of time based and determine that there has not been a steering input when the steering torque signal has not changed by at least the threshold amount during the set period of time.
