Abstract:
1. A traffic light passing support system for supporting a vehicle to pass a traffic light, the traffic light passing support system comprising: an in-vehicle apparatus provided to the vehicle; and a traffic light including a signal light and a traffic-light control unit configured to control the signal light, wherein the in-vehicle apparatus includes: wherein the traffic light includes a traffic-light receiving unit configured to receive the first request signal transmitted from the in-vehicle transmission unit, wherein the traffic-light control unit is configured to control the signal light according to the first request signal received by the traffic-light receiving unit, wherein the traffic light further includes a traffic-light transmission unit configured to transmit a signal to the in-vehicle apparatus, wherein the traffic-light control unit is further configured to: wherein the in-vehicle apparatus further includes a second arithmetic unit configured to, in response to a determination result not to accept the first request signal, calculate an in-deceleration required time, which is needed for the vehicle to arrive at the traffic light when a driver of the vehicle does not perform both braking and acceleration, according to the vehicle speed information, the present position information, the traffic light information, and a deceleration quantity when the driver does not perform both braking and acceleration, wherein the determination unit is further configured to determine whether the vehicle can pass the traffic light when decelerating by the deceleration quantity, according to the in-deceleration required time and the traffic light information, wherein the request generating unit is further configured to, in response to a determination of the determination unit that the vehicle cannot pass the traffic light when decelerating by the deceleration quantity, generate the second request signal to request the traffic light to control the signal light to light a passing permission color after the in-deceleration required time elapses, wherein the in-vehicle transmission unit is further configured to transmit the second request signal to the traffic light, and wherein the traffic-light control unit is further configured to control the signal light according to the second request signal when the traffic-light receiving unit receives the second request signal.
