[0002] During the general vehicle braking process, the brakes will generate huge friction, causing kinetic energy to be converted into resistance heat energy and wasted in the air. Electric vehicles can convert this kinetic energy wasted due to braking into electrical energy through brake energy recovery technology and store it in the power battery again, increasing the driving range. The single-pedal mode of electric vehicles only requires one power pedal to complete the acceleration and deceleration process, improving driving comfort in congested urban road conditions. However, the single-pedal control strategy in the prior art is quite different from the traditional driving mode (accelerating by pressing the accelerator and decelerating by pressing the brake), and the driver may make mistakes in emergency situations, which often cannot meet driving safety requirements. Summary of the invention

If the displacement of the driver's brake pedal is not less than the preset displacement threshold, the vehicle is controlled to start a braking and coasting coordinated energy recovery mode until the vehicle stops.

[0008] In a fifth aspect, an embodiment of the present invention provides a vehicle, comprising the vehicle safety control system described in the second aspect above.

[0009] Compared with the prior art, the present invention has the following beneficial effects: After the driver selects the single-pedal mode, it is determined whether the accelerator pedal of the vehicle is disconnected and whether the speed of the vehicle is greater than a preset vehicle threshold. When the accelerator pedal of the vehicle is disconnected and the speed of the vehicle is greater than the preset vehicle threshold, if the driver steps on the brake pedal, it is determined whether the displacement of the driver's stepping on the brake pedal is less than the preset displacement threshold. If the displacement of the driver's stepping on the brake pedal is less than the preset displacement threshold, the vehicle is controlled to start a strong coasting energy recovery mode until the vehicle stops.

[0019] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0020] See also Figure 1 , is a flow chart of a vehicle safety control method provided by Embodiment 1 of the present invention, such as Figure 1 As shown, the vehicle safety control method may include the following steps.

[0021] S101: After the driver selects the single-pedal mode, determine whether the accelerator pedal of the vehicle is disconnected and whether the vehicle speed is greater than a preset vehicle speed threshold.

[0022] In step S101, the single-pedal mode is a driving mode of an electric vehicle, which realizes the functions of acceleration, deceleration and energy recovery through the accelerator pedal. In the single-pedal mode, when the accelerator pedal is released, the driving motor of the vehicle will recover kinetic energy with a large power, thereby slowing down or stopping the vehicle. In this mode, the accelerator pedal is not only used for acceleration, but also for deceleration and stopping of the vehicle by controlling the depth of the pedal. By utilizing the motor characteristics of the electric vehicle, when the accelerator pedal is released, the motor switches from the driving mode to the power generation mode, and uses the inertia of the vehicle to drive the motor to generate electricity, converting kinetic energy into electrical energy and storing it in the battery. This energy recovery mechanism enables the single-pedal mode to provide a certain braking effect when the accelerator is released, thereby reducing the dependence on the traditional brake pedal. The single-pedal mode is the mode selected by the driver on the instrument console. After the driver selects the corresponding single-pedal mode, it is determined whether the accelerator pedal of the vehicle is disconnected and whether the vehicle speed is greater than the preset vehicle speed threshold, so as to determine the corresponding driving mode of the vehicle.

[0023] In this embodiment, after the driver selects the corresponding single-pedal mode on the instrument console, the vehicle decelerates in the single-pedal mode, and determines whether the vehicle's accelerator pedal is disconnected and whether the vehicle's speed is greater than a preset speed threshold, so as to determine the driving mode that should be turned on during the vehicle's deceleration process according to the vehicle's different driving conditions and speeds, thereby controlling the vehicle to decelerate according to the corresponding driving mode.

[0024] In this embodiment, after the driver selects the single-pedal mode, it is determined whether the accelerator pedal of the vehicle is disconnected and whether the vehicle speed is greater than a preset speed threshold, that is, the corresponding driving mode is determined according to the state of the accelerator pedal and the vehicle speed. The state of the accelerator pedal can determine whether the vehicle is accelerating. If the accelerator pedal is not disconnected, the vehicle is accelerating. If the accelerator pedal is disconnected, the vehicle is decelerating. The speed can determine the driving state of the vehicle. In the process of stopping the vehicle, it is the pedal that affects whether the vehicle is decelerating, and the speed affects the time and distance of the vehicle stopping. Therefore, the driving mode that the vehicle should be turned on can be determined according to the corresponding state of the accelerator pedal and the speed, so as to control the vehicle to turn on the corresponding mode to stop the vehicle.

[0025] S102: When the accelerator pedal of the vehicle is disconnected and the vehicle speed is greater than a preset speed threshold, if the driver steps on the brake pedal, determine whether the displacement of the driver's brake pedal is less than a preset displacement threshold.

[0026] In step S102, the accelerator pedal is disconnected, that is, the accelerator pedal is released, and the brake energy recovery system will start to work, recovering the vehicle's kinetic energy while reducing the vehicle speed. At this time, the energy recovery is mainly completed by the drag of the drive motor, and the generator stores energy to maximize the range. The vehicle is not accelerated, and the vehicle is decelerated. The vehicle speed is greater than the preset speed threshold, that is, the vehicle's driving speed before stopping is relatively high. When the vehicle's driving speed is relatively high, different modes are activated according to whether the driver steps on the brake pedal. If the driver steps on the brake pedal, the mode corresponding to the corresponding displacement is activated according to the displacement of the brake pedal. The displacement of the brake pedal is different, so that the time from the current moment to the stop of the vehicle is different, and the corresponding activated mode is different.

[0027] In this embodiment, after the driver selects the single-pedal mode, it is determined whether the vehicle's accelerator pedal is disconnected and whether the vehicle's speed is greater than a preset speed threshold. When the vehicle's accelerator pedal is disconnected and the vehicle's speed is greater than the preset speed threshold, it is further determined whether the driver has stepped on the brake pedal. If the brake pedal is stepped on, the displacement of the brake pedal, that is, the depth of the brake pedal, is determined. Different depths of the brake pedal correspond to different degrees of braking, that is, different decelerations when the vehicle decelerates, which results in different times for the vehicle to stop from the current moment and different energy recovery methods. Therefore, the mode to be activated can be determined based on the displacement of the brake pedal.

[0028] It should be noted that a brake light switch is installed on the brake pedal, see Figure 2 , is a schematic diagram of a brake pedal result provided by the second embodiment of the present invention, 1 is a travel sensor for collecting the displacement of the brake pedal, 2 is the brake pedal, and 3 is the brake light switch. When the driver steps on the brake pedal, the brake light switch is turned on and the brake light is on. When the driver does not step on the brake pedal, the brake light switch is not turned on and the brake light is off. Use the brake light to remind the driver. Optionally, after determining whether the accelerator pedal of the vehicle is disconnected and whether the vehicle speed is greater than a preset vehicle speed threshold, the method further includes: When the vehicle's accelerator pedal is disconnected and the vehicle's speed is greater than a preset speed threshold, if the driver does not step on the brake pedal, the vehicle is controlled to enter a gentle gliding energy recovery mode.

[0029] In this embodiment, when the accelerator pedal of the vehicle is disconnected and the vehicle speed is greater than the preset speed threshold, if the driver does not step on the brake pedal, that is, the brake light switch is not turned on and the brake light is not on, the vehicle is controlled to start the soft gliding energy recovery mode, so that the deceleration of the vehicle during deceleration is less than 1 , even if the vehicle is decelerating at a smaller deceleration.

[0030] Optionally, after controlling the vehicle to start the gentle gliding energy recovery mode, the method further includes: When the vehicle speed is not greater than a preset vehicle threshold, the vehicle is controlled to stop the gentle gliding energy recovery mode.

[0031] In this embodiment, after the vehicle is controlled to start the soft coasting energy recovery mode, the vehicle The vehicle is decelerated at a deceleration rate. When the vehicle decelerates to a speed no greater than a preset vehicle threshold, the vehicle is controlled to stop the gentle gliding energy recovery mode and to enter an idling driving state.

[0032] Optionally, after controlling the vehicle to start the gentle gliding energy recovery mode, the method further includes: A first voice is generated according to the gentle gliding energy recovery mode to provide voice prompts to the driver.

[0033] In this embodiment, the vehicle is provided with a voice prompt. When the soft glide energy recovery mode is turned on, a first voice is generated according to the soft glide energy recovery mode to give a voice prompt to the driver. The first voice may be "The soft glide energy recovery mode is activated. If a strong deceleration is required, please put your right foot on the brake" to remind the driver whether to brake to stop. The first voice may also be other voices, which are not limited in this embodiment.

[0034] S103: If the displacement of the driver's brake pedal is less than the preset displacement threshold, the vehicle is controlled to start the strong coasting energy recovery mode until the vehicle stops. If the displacement of the driver's brake pedal is not less than the preset displacement threshold, the vehicle is controlled to start the braking and coasting coordinated energy recovery mode until the vehicle stops.

[0035] In step S103, if the displacement of the driver's brake pedal is less than the preset displacement threshold, the vehicle is controlled to decelerate at a smaller deceleration, and the vehicle is controlled to start a strong coasting energy recovery mode until the vehicle stops. If the displacement of the brake pedal is not less than the preset displacement threshold, the vehicle is controlled to start a braking and coasting coordinated energy recovery mode until the vehicle stops.

[0036] In this embodiment, if the displacement of the driver's brake pedal is less than the preset displacement threshold, the vehicle is controlled to start the strong coasting energy recovery mode, wherein the preset displacement threshold may be 5mm, or other values, which are not limited in this embodiment. -3 The displacement of the brake pedal is less than the preset displacement threshold, that is, when the vehicle decelerates slowly, the corresponding deceleration is small.

[0037] If the displacement of the brake pedal is not less than the preset displacement threshold, the vehicle is controlled to start the braking and coasting coordinated energy recovery mode until the vehicle stops. The displacement of the brake pedal is not less than the preset displacement threshold, that is, the displacement of the brake pedal is large, that is, the displacement of the brake pedal is greater than 5mm, the braking intention is strong, and the braking deceleration is greater than 3 , or greater than other deceleration values, which is not limited in this embodiment.

[0038] Optionally, after controlling the vehicle to start the strong coasting energy recovery mode, the method further includes: A second voice is generated according to the strong coasting energy recovery mode to provide voice prompts to the driver.

[0039] In this embodiment, the vehicle is provided with a voice prompt. When the strong coasting energy recovery mode is turned on, a second voice is generated according to the strong coasting energy recovery mode to give a voice prompt to the driver. The second voice may be "Strong coasting mode is activated, please pay attention to the situation ahead and brake in time". The second voice may also be other voices, which are not limited in this embodiment.
