Example 1
Fig. 1 is a flowchart of a gear control method according to an embodiment of the present invention. The present embodiment is applicable to a case where an appropriate gear of a transmission is accurately determined and the gear of the transmission is controlled to be shifted to the appropriate gear during running of a vehicle, and the method may be performed by a gear control device which may be implemented in hardware and/or software, and which may be configured in a transmission control unit provided on the vehicle. The transmission control unit is an electronic device for controlling the gear position of the transmission. The transmission control unit may be a controller provided on the vehicle and dedicated to controlling the gear of the transmission, or may be a vehicle control unit of the vehicle. As shown in fig. 1, the method includes:
and 101, determining a target gear of the transmission according to the current working state, the current vehicle speed and the current gear shifting information of the electronic parking brake system at fixed time.
Optionally, the electronic parking brake system is an electronic control system arranged on the vehicle and used for realizing parking brake by using an electronic control mode. The current operating state of the electronic parking brake system is the operating state of the electronic parking brake system at the current moment. The working state of the electronic parking brake system is a pulled-up state, a released state or an unknown state. The operating state of the electronic parking brake system being in the pulled state means that the electronic parking brake system is executing a parking action. The operating state of the electronic parking brake system being a released state means that the electronic parking brake system stops executing the parking action. The operating state of the electronic parking brake system being an unknown state means that it is impossible to determine whether the operating state of the electronic parking brake system is a pulled-up state or a released state. The transmission control unit establishes communication connection with the electronic parking brake system, and information interaction can be performed based on the established communication connection. The transmission control unit may obtain a current operating state of the electronic parking brake system from the electronic parking brake system.
Optionally, the current vehicle speed is a vehicle speed of the vehicle at the current time. The transmission control unit establishes communication connection with a vehicle speed sensor arranged on the vehicle, and information interaction can be performed based on the established communication connection. The transmission control unit may acquire the current vehicle speed from a vehicle speed sensor.
Optionally, the current shift information is shift information at the current time. The shift information is information input by the driver of the vehicle for instructing the transmission to shift gears. The shift information contains the driver's desired gear. The driver desired gear is the gear to which the driver needs to shift the transmission. The driver may input shift information to the transmission control unit via an electronic shifter or key.
Alternatively, the target gear of the transmission is a suitable gear of the transmission, i.e. a gear of the transmission suitable for the current vehicle conditions. The gear of the transmission may be a park gear, a reverse gear, a neutral gear or a forward gear.
Optionally, determining the target gear of the transmission according to the current working state, the current vehicle speed and the current gear shifting information of the electronic parking brake system at regular time includes: the method comprises the steps of acquiring the current working state of an electronic parking brake system at regular time according to a preset time interval; and if the current working state of the electronic parking brake system is a pulled-up state, determining that the target gear of the transmission is a parking gear.
Optionally, the transmission control unit acquires a current working state of the electronic parking brake system once at intervals of a preset time, so as to start a determining process of determining the target gear of the transmission according to the current working state, the current vehicle speed and the current gear shifting information of the electronic parking brake system. The preset time interval may be set according to the service requirement. The preset time interval is, for example, 1 minute.
Alternatively, in a normal case, when the current working state of the electronic parking brake system is a pulled state, the electronic parking brake system is executing a parking action, and the gear of the transmission needs to be kept at a parking gear. Therefore, if the current working state of the electronic parking brake system is a pulled-up state, the target gear of the transmission is directly determined to be the parking gear.
Optionally, after the current working state of the electronic parking brake system is acquired at regular time according to a preset time interval, the method further includes: if the current working state of the electronic parking brake system is an unknown state, acquiring a current vehicle speed, and detecting whether the current vehicle speed is smaller than a preset vehicle speed threshold value or not; and after detecting that the current vehicle speed is smaller than the preset vehicle speed threshold value, determining that the target gear of the transmission is a parking gear.
Optionally, after detecting whether the current vehicle speed is less than a preset vehicle speed threshold, the method further includes: and after detecting that the current vehicle speed is greater than or equal to the preset vehicle speed threshold, determining that the target gear of the transmission is a neutral gear.
Alternatively, in a normal case, when the current working state of the electronic parking brake system is an unknown state, it cannot be determined whether the working state of the electronic parking brake system is a pulled-up state or a released state. If the vehicle speed is at a low value at this time, the gear of the transmission needs to be maintained in the park position. If the vehicle speed is not at a lower value at this time, the transmission gear needs to be maintained in neutral. Therefore, under the condition that the current working state of the electronic parking brake system is an unknown state, the current vehicle speed is obtained, and whether the current vehicle speed is smaller than a preset vehicle speed threshold value or not is detected. And if the current vehicle speed is detected to be smaller than the preset vehicle speed threshold value, indicating that the vehicle speed is at a lower value at the moment, determining that the target gear of the transmission is the parking gear. And if the current vehicle speed is detected to be greater than or equal to the preset vehicle speed threshold value, and the vehicle speed is not at a lower value, determining that the target gear of the transmission is a neutral gear. The preset vehicle speed threshold can be set according to the service requirement. The preset vehicle speed threshold is, for example, 3 km/h.
Optionally, after the current working state of the electronic parking brake system is acquired at regular time according to a preset time interval, the method further includes: if the current working state of the electronic parking brake system is a release state, acquiring current gear shifting information; and after the current gear shifting information is acquired, extracting a driver expected gear from the current gear shifting information, and determining a target gear of the transmission according to the driver expected gear.
Optionally, determining the target gear of the transmission according to the driver desired gear includes: if the driver expects that the gear is a reverse gear, determining that the target gear of the transmission is the reverse gear; if the driver expects that the gear is a neutral gear, determining that the target gear of the transmission is the neutral gear; if the driver expects that the gear is a forward gear, determining that the target gear of the transmission is the forward gear; and if the driver expected gear is a parking gear, determining that the target gear of the transmission is a neutral gear.
Optionally, after acquiring the current shift information, the method further includes: and if the current gear shifting information is not acquired, determining that the target gear of the transmission is the current gear.
Alternatively, in a normal case, when the current working state of the electronic parking brake system is a release state, the electronic parking brake system stops executing the parking action, and the gear of the transmission may be other gears except for the parking gear. If the current shift information is received at this time and the driver desired gear in the current shift information is other than the park gear, the transmission needs to be shifted to the driver desired gear. If the current gear shifting information is received at this time and the driver expected gear in the current gear shifting information is the parking gear, the gear of the transmission cannot be the parking gear, and the gear of the transmission needs to be kept as the neutral gear. If no current shift information is received at this time, i.e. the driver does not input shift information at the current time, the gear of the transmission needs to be kept at the current gear of the transmission. Therefore, under the condition that the current working state of the electronic parking brake system is a release state, current gear shifting information is acquired. After the current gear shifting information is acquired, a driver expected gear is extracted from the current gear shifting information, and a target gear of the transmission is determined according to the driver expected gear: if the driver expects that the gear is a reverse gear, determining that the target gear of the transmission is the reverse gear; if the driver expects that the gear is a neutral gear, determining that the target gear of the transmission is the neutral gear; if the driver expects that the gear is a forward gear, determining that the target gear of the transmission is the forward gear; and if the driver expected gear is a parking gear, determining that the target gear of the transmission is a neutral gear. And if the current gear shifting information is not acquired, determining that the target gear of the transmission is the current gear.
Optionally, if the obtained current gear shifting information is invalid information, determining that the target gear of the transmission is a neutral gear.
Optionally, if the transmission control unit cannot acquire the current working state of the electronic parking brake system from the electronic parking brake system, it is determined that the electronic parking brake system is abnormal, and the preset numerical information is sent to the transmission. The preset numerical value information is used for indicating that the electronic parking brake system is abnormal. The transmission maintains the current gear after receiving the preset numerical information.
Step 102, detecting whether the current gear of the transmission is the same as the target gear.
Optionally, the current gear of the transmission is the gear of the transmission at the current moment. The transmission control unit establishes a communication connection with the transmission, and information interaction can be performed based on the established communication connection. The transmission control unit may acquire a current gear of the transmission from the transmission, and detect whether the current gear of the transmission is the same as the target gear.
Step 103, if the current gear of the transmission is different from the target gear, controlling the gear of the transmission to be switched from the current gear to the target gear.
Optionally, if the current gear of the transmission is different from the target gear, it indicates that the gear of the transmission at the current moment is not a gear of the transmission suitable for the current vehicle condition, and it is required to control the gear of the transmission to be switched from the current gear to the target gear.
Optionally, the transmission, after receiving the gear sent by the transmission control unit, will switch the gear of the transmission from the current gear to the received gear.
Optionally, controlling the shift of the transmission from the current shift to the target shift includes: the target gear is transmitted to the transmission so that the transmission shifts the gear of the transmission from the current gear to the target gear after receiving the target gear.
Optionally, if the current gear of the transmission is the same as the target gear, which indicates that the gear of the transmission at the current moment is a gear of the transmission suitable for the current vehicle condition, and the transmission is not required to be controlled to switch the gear, the end of the current gear control flow is determined, and the next time of determining the target gear of the transmission according to the current working state, the current vehicle speed and the current gear shifting information of the electronic parking brake system is waited.
According to the technical scheme, the target gear of the transmission is determined according to the current working state, the current vehicle speed and the current gear shifting information of the electronic parking brake system at regular time; detecting whether the current gear of the transmission is the same as the target gear; under the condition that the current gear of the transmission is different from the target gear, the gear of the transmission is controlled to be switched from the current gear to the target gear, the problem that the gear control scheme in the related art does not comprehensively judge according to key data influencing the proper gear of the transmission, such as the working state and the speed of an electronic parking brake system of a vehicle, and the proper gear of the transmission cannot be accurately determined is solved, the comprehensive judgment can be carried out according to the current working state and the current speed of the electronic parking brake system and current gear shifting information at regular time, the gear of the transmission suitable for the current vehicle condition is accurately determined, and the gear of the transmission is controlled to be switched from the current gear to the gear of the transmission suitable for the current vehicle condition when the gear of the transmission at the current moment is not the gear of the transmission suitable for the current vehicle condition, so that the proper gear of the transmission is accurately determined according to the working state and the key data influencing the proper gear of the transmission, such as the speed of the electronic parking brake system of the vehicle, in the vehicle driving process of the vehicle is realized, and the proper gear of the transmission is accurately determined based on the proper gear of the transmission is controlled.
