The various embodiments herein provide a reverse gear sensor and alert device for a vehicle comprising an electronic hub, a motor and a tail. The electronic hub comprises a control electronics circuitry (CEC), an audible buzzer, and an ultrasonic buzzer. The electronic hub is installed over a base frame attached to a rear body of the vehicle and is connected with a power source. The tail is attached to the electronic hub through the motor. The tail comprises a plurality of illumination members fixed on an outer surface of the tail and are powered through the motor. The power supply allows a flow of current to the motor on detecting a reverse gear activation in the vehicle. The current flow energizes the motor leading to a protrusion of the tail out of the vehicle. The plurality of illumination members, the audible buzzer, and the ultrasonic buzzer are activated on activation of the reverse gear.

A driving support apparatus estimates an expected route of an own vehicle, calculates an effective length of the expected route, and alerts a driver of the own vehicle when it is determined that there exists an object which crosses a part within the effective length within a predetermined time. A formula of a circle with a radius of an estimated turning radius is used for an expected route formula expressing the expected route. Once it is determined that the own vehicle is trying to start turning left or right, the driving support apparatus calculates a turning angle of the own vehicle, and calculates the effective length of the expected route using a value based on a product of the estimated turning radius and a remaining turning angle which is an angle obtained by subtracting the turning angle from a predetermined angle.

A lighting device for motor vehicles designed to emit light in a main direction of emission. The lighting device has at least one vane mounted with the ability to move in the lighting device, the vane having a panel on which at least one area light source is arranged.
