The following describes a method and a device for reminding sliding of an electric vehicle and the electric vehicle according to the embodiments of the present application with reference to the accompanying drawings. In order to solve the problems that the current vehicle sliding reminding accuracy is poor and the vehicle sliding reminding cannot be performed in a power-off state of the vehicle, the application provides a vehicle sliding reminding method of an electric vehicle, wherein in the method, when the electric vehicle moves and a power supply is turned off, a vehicle sliding signal is sent to remind a user of vehicle sliding so as to realize the vehicle sliding reminding when the electric vehicle is powered off; when the electric automobile moves and the power is turned on, when the vehicle is in a neutral gear within a certain time, and the actual speed is not zero, the slipping of the electric automobile is judged, so that whether the vehicle slips can be judged by combining a plurality of conditions of the electric automobile, whether the vehicle slips can be judged accurately and reliably, and the accuracy of vehicle slipping reminding is improved. From this, solved present swift current car and reminded the accuracy relatively poor, and can't carry out swift current car under the vehicle state of cutting off the electricity and remind the scheduling problem.
Specifically, fig. 1 is a schematic flow chart of a method for reminding a user of rolling a vehicle of an electric vehicle according to an embodiment of the present application.
As shown in fig. 1, the method for reminding the electric vehicle to roll comprises the following steps:
in step S101, it is detected whether the electric vehicle is moving.
The execution main body of the method for reminding the user of sliding the electric automobile can be the electric automobile. The method for reminding the electric vehicle to slide can be executed by the device for reminding the electric vehicle to slide in the embodiment of the application, and the device for reminding the electric vehicle to slide in the embodiment of the application can be configured in any electric vehicle to execute the method for reminding the electric vehicle to slide in the embodiment of the application. The execution main body of the electric vehicle sliding reminding method can be a T-Box (Telematics BOX) in the electric vehicle.
It can be understood that, in the embodiment of the application, whether the electric vehicle moves is taken as one of the conditions for judging the vehicle slipping, so that the accuracy of vehicle slipping judgment can be improved. The embodiment of the application can detect whether the electric automobile moves in various ways, for example, a six-axis sensor or a displacement sensor.
Taking a six-axis sensor as an example, the T-Box is internally provided with the six-axis sensor, the T-Box and the six-axis sensor are communicated through a serial port, and when the six-axis sensor detects that the vehicle moves, a hard-line signal is sent to the T-Box so as to detect whether the electric vehicle moves.
In step S102, when it is detected that the electric vehicle moves and the power of the electric vehicle is turned off, a vehicle sliding signal is sent to a preset terminal.
It can be understood that, this application embodiment can still can carry out swift current car when electric automobile cuts off the electricity and remind, has effectively solved the defect that can't carry out swift current car when electric automobile cuts off the electricity and reminds, can improve user's use and experience.
Wherein, other terminals or APP etc. that preset terminal can set up for user's mobile terminal, user for example, when electric automobile swift current the car, can in time remind the user to swift current the car through the characters bullet frame with swift current car signal transmission to APP on.
For example, a BCM (Body Control Module, a vehicle Body controller) sends a power supply gear of a whole vehicle to a T-Box through a CAN bus, if the T-Box judges that the power supply gear is an OFF gear, a user CAN be considered not to send a vehicle slipping signal to a TSP (Telematics Service Provider) platform for remote vehicle slipping reminding, and after the TSP platform receives the vehicle slipping signal sent by the T-Box, the user is reminded of current vehicle slipping through short messages or phone or APP text boxes and other forms, so that vehicle slipping judgment CAN be still carried out when the power supply is turned OFF, the user is reminded remotely and timely when the vehicle slips, and the use experience of the user is improved.
In step S103, when it is detected that the electric vehicle moves and the power of the electric vehicle is turned on, acquiring an actual vehicle speed and a current gear of the electric vehicle, determining that the electric vehicle rolls, and controlling the vehicle-mounted reminding assembly to carry out vehicle rolling reminding when the current gear is in a neutral gear and the actual vehicle speed is not zero within a preset time.
The preset duration can be set according to actual conditions, and is not particularly limited.
It can be understood that when the electric automobile moves and is in a power-on state, if the current gear is in a neutral gear within a certain time and the actual speed is not zero, the electric automobile can be determined to slide, and sliding reminding is performed; and when the current gear is detected to exit from the neutral gear or the actual vehicle speed is zero, controlling the vehicle-mounted reminding assembly to cancel vehicle sliding reminding. The embodiment of the application can judge whether the vehicle slips according to a plurality of conditions of the electric automobile, so that the vehicle slips can be accurately and reliably judged, and the accuracy of vehicle slipping reminding is improved.
For example, a VCU (Vehicle Control Unit) sends a Vehicle speed signal and a gear signal to a T-Box through a CAN bus, a BCM sends a power gear of the whole Vehicle to the T-Box through the CAN bus, and if the T-Box judges that the power gear is an ON gear, a user CAN be considered not to send a Vehicle sliding signal to a TSP platform ON the Vehicle to carry out remote Vehicle sliding reminding, so that the intelligence of Vehicle sliding reminding is improved. If the gear in the preset time length T1 is neutral and the condition that the vehicle speed is greater than 0 is met, the T-Box judges that the current vehicle meets the vehicle sliding condition and sends a vehicle sliding signal to the vehicle-mounted reminding assembly; if the preset time T1 is that the gear is not neutral or the vehicle speed is 0 and a condition is met, the T-Box judges that the current vehicle does not meet the vehicle sliding condition and sends a vehicle sliding cancellation signal to the vehicle-mounted reminding assembly.
In this embodiment, on-vehicle warning subassembly includes acoustics reminding device, characters reminding device and optics reminding device, controls on-vehicle warning subassembly and carries out swift current car warning, includes: sending a vehicle sliding signal to a vehicle body controller and a navigation host; and controlling the navigation host to drive the acoustic reminding device and/or the text reminding device to carry out in-vehicle sliding reminding, and controlling the vehicle body controller to drive the optical reminding device to carry out sliding reminding on pedestrians and other vehicles.
Wherein, acoustics reminding device can be the speaker, and characters reminding device can be vehicle-mounted screen, and optics reminding device can be danger alarm lamp. This application embodiment can in time remind user and pedestrian and other vehicles in the car through modes such as dangerous alarm lamp, pronunciation, characters bullet frame when electric automobile moves away the car, eliminates the potential safety hazard that the swift current car brought.
For example, a database is arranged in a DVD (navigation host), the DVD and the database are communicated through a serial port, the database stores CAN message instructions and voice signals corresponding to the CAN message instructions, and when a car rolling signal/car rolling canceling signal sent by a T-Box is received, a loudspeaker is driven to play/cancel the voice play through the serial port; the BCM receives a vehicle sliding signal/vehicle sliding cancellation signal sent by the T-Box, and the danger alarm lamp is driven/cancelled to work through a serial port hard wire high-low level signal so as to remind surrounding vehicles and pedestrians to notice avoidance.
In some embodiments, after controlling the vehicle-mounted reminding assembly to carry out vehicle-sliding reminding, the method further comprises: detecting the actual distance between the electric automobile and a rear obstacle; and when the actual distance is smaller than the safe distance, matching the corresponding braking torque according to the actual speed so as to brake the electric automobile.
It can be understood that, the embodiment of the application can detect the distance between the electric automobile and a rear obstacle in real time when the automobile slides, and adjust the braking force in real time to brake, so that collision caused by sliding is avoided, and the reliability of the automobile is improved.
For example, the RCM (Range Cell distribution, radar controller) receives a T-Box roll signal to drive the probe to measure a distance L1 between a current vehicle and a rear obstacle, and sends the distance to the T-Box through a CAN bus, and if the T-Box does not detect that the condition is not met within a preset time or the RCM sends the distance less than a safe distance, the RCM sends a corresponding braking force signal to an Electronic Stability Program (ESP) according to the current vehicle speed; and after receiving the braking force signal sent by the T-Box, the ESP drives the brake to brake. According to the embodiment of the application, when the L1 is detected to be smaller than the safety distance in the preset time T3, the braking force is adjusted in real time according to L1 to brake.
In some embodiments, the vehicle sliding reminding can be performed through the vehicle sliding reminding system shown in fig. 2, and the embodiment of the application can be developed based on a certain new energy automobile, so that the utilization rate of the whole vehicle resources is high. As shown in fig. 2, the rolling reminding system includes: six-axis sensors, T-Box, VCU, BCM, RCM, ESP, DVD, database, TSP platform, hazard warning lights, probes, speakers, and APP. The T-Box, the VCU, the BCM, the RCM, the ESP and the DVD CAN carry out data communication through a CAN bus; the TSP platform, the APP and the T-Box can communicate through a 4G wireless network. Wherein, the T-Box, VCU, BCM, RCM, ESP and DVD software has the function of network management; enabling or forbidding enabling the sliding reminding by a built-in soft switch of the DVD, if the switch state is enabled, starting the sliding reminding system, and if the switch state is forbidding enabling, closing the sliding reminding system.
