Driving support apparatus for vehicle
View Patent ↗In a driving support apparatus for a vehicle, when a driver indicates the intension to turn by turning a turn signal switch on, vehicles traveling on a lane to which the driver intends to turn is detected based on images captured by monitoring cameras, a space to cut into between the vehicles is calculated, an entry start time of a subject vehicle is obtained based on a speed difference between a speed of the subject vehicle and a moving speed of the space to cut into, and, when the entry start time is reached, voice guidance instructing to start turning is output from an instruction unit.
1. A driving support apparatus for a vehicle, comprising:
a turn signal switch to be operated when making a turn;
a traveling condition imaging unit configured to capture road traveling conditions around a subject vehicle;
a vehicle speed detecting unit configured to detect a vehicle speed of the subject vehicle; and
a calculating unit configured to set a timing to start turning and a specified vehicle speed for turning, wherein
the calculating unit includes:
a driving lane condition detecting unit configured to check which one of a right turn switch and a left turn switch of the turn signal switch is turned on when the turn signal switch is turned on, detect traveling conditions of vehicles traveling on the turned-on switch side based on the road traveling conditions captured by the traveling condition imaging unit and detect a space to cut into based on the detection result of the road traveling conditions; and
a vehicle entry timing detecting unit configured to obtain an entry start time at which the subject vehicle is to enter the space to cut into, and output an entry start instruction signal to an instruction unit when the entry start time is reached.
2. The driving support apparatus for a vehicle according to claim 1 , wherein the instruction unit is a display unit.
3. The driving support apparatus for a vehicle according to claim 1 , wherein the instruction unit is a voice guidance unit.
4. The driving support apparatus for a vehicle according to claim 1 , wherein the driving lane condition detecting unit determines whether or not the subject vehicle can cut into by comparing an actual distance in a front-back direction of the space to cut into with a predetermined required distance for the subject vehicle to cut into.
5. The driving support apparatus for a vehicle according to claim 1 , wherein the vehicle entry timing detecting unit sets the entry start time based on a speed difference between the vehicle speed of the subject vehicle and a moving speed of the space to cut into.
6. The driving support apparatus for a vehicle according to claim 1 , wherein the vehicle entry timing detecting unit outputs a countdown time to the entry start time to the instruction unit.
7. The driving support apparatus for a vehicle according to claim 6 , wherein the instruction unit is the display unit.
8. The driving support apparatus for a vehicle according to claim 6 , wherein the instruction unit is the voice guidance unit.
9. The driving support apparatus for a vehicle according to claim 6 , wherein the vehicle entry timing detecting unit outputs the specified vehicle speed for turning to a specified vehicle speed display unit when the countdown time is output.
