Provided is an electronic parking brake system including: an electronic parking brake provided in at least one of a front wheel and a rear wheel of a vehicle and driven by a motor; and a controller electrically connected to the motor, wherein the controller is configured to determine whether a gear stage of an electronic transmission system (a shift by wire: SBW) is shifted to a neutral position during ignition-off of the vehicle, and upon determining that the gear stage is shifted to the neutral position, release engagement of the electronic parking brake.

This drive assistance device comprises an ACC unit, an abnormality detection unit for detecting an abnormality from a detector used to perform ACC, and a vehicle stop control unit for performing control to stop an ego vehicle when an abnormality is detected by the abnormality detection unit and an inter-vehicle distance to a preceding vehicle satisfies a certain condition.

Systems and methods use cameras to provide autonomous navigation features. In one implementation, a method for navigating a user vehicle may include acquiring, using at least one image capture device, a plurality of images of an area in a vicinity of the user vehicle; determining from the plurality of images a first lane constraint on a first side of the user vehicle and a second lane constraint on a second side of the user vehicle opposite to the first side of the user vehicle; enabling the user vehicle to pass a target vehicle if the target vehicle is determined to be in a lane different from the lane in which the user vehicle is traveling; and causing the user vehicle to abort the pass before completion of the pass, if the target vehicle is determined to be entering the lane in which the user vehicle is traveling.

Provided is an electric braking device that transmits power generated by an electric motor MTR to a pressing member PSN and causes pressing force to be generated by the pressing member PSN with respect to a friction member MSB. Hysteresis characteristics in the relation between the power supply amount to the electric motor and the pressing force of the pressing member are detected each time a predetermined point in time arrives. Upon determination of a “holding state in which the pressing force is held constant”, a minimum value for a power supply amount that makes it possible to maintain the current pressing force is obtained on the basis of the most recently detected hysteresis characteristics and the power supply amount is set to a value determined on the basis of the obtained minimum value for the power supply amount.

An emergency braking control circuit based on coupler coupling detection includes a coupler status detection circuit and a coupler status relay that are connected in series with a train power loop. A normally open contact of the coupler status relay is connected to an emergency braking train line in a cross-parallel manner. When a coupler is coupled normally, inductive proximity sensors located at a knuckle and a central pivot are closed to drive the coupler status relay, and the normally open contact of the coupler status relay is connected in a cross-parallel manner to ensure that a corresponding node of the emergency braking loop is closed. In case of abnormal coupling or accidental uncoupling of couplers, the inductive proximity sensors of the couplers of two adjacent cars are disconnected simultaneously, the coupler status relays of the two cars are powered off, and emergency braking is applied.

A vehicle operable by an unrestrained or uncontained rider and including a controller programmed to identify a trigger for an autonomous vehicle response. A sensor of the vehicle is in communication with the controller and operable to detect a predefined condition as the trigger. A rider sensor system in communication with the controller includes one or both of: a rider cognition sensor, and a rider physical sensor to detect physical engagement between rider and vehicle. On the condition of the controller determining from the rider sensor system that there is positive rider engagement, the controller is programmed to instruct a first level of autonomous vehicle response to the one or more actuators to effect a change in the operation of the vehicle in response to identification of the trigger. In the absence of positive rider engagement determined by the controller, the first level of autonomous vehicle response is prohibited.
