5 . The driving intention indicating device of claim 4 , wherein when an object is sensed by the sensor, the control unit is configured to control the projection system to project a warning image on a road surface close to the vehicle, wherein the warning image comprises at least one of a flashing image, a warning symbol and a warning text.
6 . The driving intention indicating device of claim 4 , wherein when an object is sensed by the sensor, the control unit is configured to control a speaker to generate a warning voice outside of the vehicle.
7 . The driving intention indicating device of claim 1 , wherein the control unit is further configured to control the projection system to project a turn indicating image on a road surface close to a side of a turning direction of the vehicle according to a turning instruction.
8 . The driving intention indicating device of claim 7 , wherein the turn indicating image comprises at least one of a turning symbol, a turning arrow film and a turn indicating text.
9 . The driving intention indicating device of claim 7 , wherein the turning instruction is generated by at least one of a gesture input, a voice input, a touch input, a trigger signal of the turn signal lights and a trigger signal of a button.
10 . The driving intention indicating device of claim 1 , wherein the control unit is further configured to control the projection system to project a lane change indicating image on a road surface close to a side of a changing lane direction of the vehicle according to a lane changing instruction.
11 . The driving intention indicating device of claim 10 , wherein the lane change indicating image comprises at least one of a lane changing symbol, a lane changing arrow film and a lane changing indicating text.
12 . The driving intention indicating device of claim 10 , wherein the lane changing instruction is generated by at least one of a gesture input, a voice input, a touch input, a trigger signal of the turn signal lights and a trigger signal of a button.
13 . A driving intention indicating method, comprising:
providing a projection system arranged on a vehicle;
detecting a change in a gear position of a gearbox of the vehicle; and
when the gear position of the gearbox of the vehicle is switched from a first gear position to a second gear position, controlling the projection system to project an indicating image on a road surface close to the vehicle according to a moving direction of the second gear position, in order to indicate a moving direction of the vehicle from a parked position.
14 . The driving intention indicating method of claim 13 , wherein when the second gear position is a drive gear position, controlling the projection system to project the indicating image on a road surface in front of the vehicle.
15 . The driving intention indicating method of claim 13 , wherein when the second gear position is a reverse gear position, controlling the projection system to project the indicating image on a road surface at the rear of the vehicle.
16 . The driving intention indicating method of claim 13 , further comprising:
providing a sensor configured to sense objects located in an edge of the indicating image on the road surface projected by the projection system; and
when an object is sensed by the sensor, generating a warning signal outside of the vehicle.
