Fig. 1 shows an electric vehicle energy recovery system work reminding device according to an embodiment of the disclosure. As shown in fig. 1, the device includes an accelerator pedal sensor 1, a brake pedal sensor 2, a CAN module 3, a control chip 4, a rear camera 5, and a rear warning lamp 6. The vehicle tail warning lamp 6 can be an LED warning lamp. In the device, an accelerator pedal sensor 1 records pedal position and position change rate information in real time, a brake pedal sensor 2 records pedal position information in real time, and the information is transmitted to a CAN module 3 in real time through a CAN bus to carry out signal interconnection and interaction; the vehicle speed information on the CAN bus of the vehicle CAN be directly obtained in real time according to the judgment condition required by the system work; the control chip 4 is the exclusive controller of the work reminding device of the energy recovery system of the electric automobile, the control chip 4 extracts the accelerator pedal sensor 1, the brake pedal sensor 2 and the speed information gathered in the CAN module 3 in real time as input signals, and simultaneously extracts the real-time rear distance information acquired by the rear camera 5 in real time as a second path of input signals as system work judgment conditions to control whether the rear warning lamp 6 is lightened for work.
A work process of electric automobile energy recovery system work reminding device:
1) when the speed of a vehicle is lower than 20 kilometers per hour, the control chip 4 judges that the vehicle is in a creeping state at the moment according to the collected speed information, the dragging effect of the energy recovery system of the electric vehicle during working is not obvious, the device cannot work, the tail warning lamp 6 cannot be lightened, and the tail warning lamp and the brake lamp do not have mutual influence.
2) When the speed of a motor vehicle is higher than 20 kilometers per hour, control chip 4 judges this moment the vehicle is normal driving state according to the speed of a motor vehicle information of collecting back, and electric automobile energy recovery system can produce the comparatively obvious effect of pulling of different degrees during operation, and the device gets into the activated state, and rear of a vehicle camera 5 starts to the rear of a vehicle position information feedback who obtains in real time is to control chip 4, and rear of a vehicle warning light 6 lights work according to following condition:
further, if the vehicle distance is more than or equal to 20 meters after the judgment of the vehicle tail camera 5, the control chip 4 considers that no potential rear-end collision risk exists, the system enters a standby state, and then the vehicle tail warning lamp 6 cannot be lightened no matter what actions are taken by the accelerator pedal 1 and the brake pedal 2;
if the vehicle tail camera 5 judges that the vehicle distance is less than 20 meters, the control chip 4 considers that the potential rear-end collision risk exists at the current vehicle speed; the position and the position variation information of the accelerator pedal 1 and the position information of the brake pedal 2 which need to be acquired in real time are used as further judgment conditions, so that whether the tail warning lamp 6 of the vehicle is lightened or not is determined, and the attention of the vehicle behind is reminded in time.
Further, if the accelerator pedal is rapidly lifted to a completely released position at this time, the accelerator pedal sensor 1 detects a position change and has a large change rate; and the brake pedal is not stepped on within 0.5 second, namely the brake pedal sensor 2 does not detect the position change, the control chip 4 considers that the obvious energy recovery dragging phenomenon exists at the moment, and then judges that the larger rear-end collision risk exists, and the control vehicle tail warning lamp 6 is lightened at the moment to remind the rear vehicle to keep the vehicle distance.
If the accelerator pedal is rapidly lifted to a completely released position, the accelerator pedal sensor 1 detects a position change and has a larger change rate; but brake pedal is stepped on rapidly this moment, and brake pedal sensor 2 detects the position promptly, and control chip 4 thinks that vehicle braking system has worked this moment, and the rear of a vehicle brake light has lighted and reminds the back car, and then judges need not to intervene and light this system rear of a vehicle warning light 6, avoids causing the conflict of system work logic.
If the accelerator pedal is slowly lifted up at this moment, namely, the accelerator pedal sensor 1 detects the position change, but the position change rate is not obvious, the brake pedal is not stepped on at this moment, namely, the brake pedal sensor 2 does not detect the position change, the control chip 4 considers that the driver is effectively carrying out vehicle speed control at this moment, the electric automobile energy recovery system does not work at this moment, and then the judgment is carried out without intervention and the vehicle tail warning lamp 6 of the system is lightened.
The above examples mainly illustrate the utility model discloses an evaluation system for vehicle road test completion quality. Although only a few embodiments of the present invention have been described, those skilled in the art will appreciate that the present invention may be embodied in many other forms without departing from the spirit or scope thereof. Accordingly, the present examples and embodiments are to be considered as illustrative and not restrictive, and various modifications and substitutions may be made thereto without departing from the spirit and scope of the present invention as defined by the appended claims.
