Embodiment approach

[0089] In a feasible implementation manner, when the gear state indicates that the vehicle is in static gear, a rotational speed threshold corresponding to the static gear is generated according to the preset maximum adjusted rotational speed and the first value.

[0090] Exemplarily, the HCU can determine whether the current gear state of the vehicle is a static gear according to the current vehicle speed information obtained in step 201. If the current vehicle speed value represented by the current vehicle speed information is less than or equal to a preset threshold, the preset threshold is 0, Then it is determined that the gear state of the vehicle is static in gear.

[0091] When the gear state of the vehicle is in static gear, the HCU can generate a speed threshold corresponding to the static gear according to the preset maximum adjustment speed and the first value, wherein the preset maximum adjustment speed is a preset value, which is represented by n_spdadj_max, The p...

Abstract

The present application provides a control method, device and medium for shifting an engine mode in a parallel system. The method includes: acquiring required gear information, and determining a target rotational speed of a gearbox in a vehicle according to the required gear information; The target rotational speed generates a control signal, and sends the control signal to the motor controller of the vehicle, and the control signal is used by the motor controller to control the motor of the vehicle to operate according to the control signal to adjust the motor controller. The speed of the gearbox; when it is determined that the speed of the gearbox is within a preset speed range, the gearbox is controlled to engage in gear. With the method provided in the present application, the time for shifting and speed regulation in the engine mode of the parallel system can be shortened, thereby shortening the time of power interruption of the vehicle, and improving the quality of shifting.

Description

technical field [0001] The present application relates to the shifting technology of automobile engine, and in particular, to a control method, device and medium for shifting the engine mode of a parallel system. Background technique [0002] When the vehicle is equipped with a parallel hybrid power system, when shifting under the parallel hybrid power system, due to the relatively large moment of inertia of the motor of the vehicle, the time for shifting and speed regulation is long. [0003] In the prior art, the engine oil of the vehicle can be cut off and the vehicle can be decelerated naturally. [0004] However, in the prior art, the natural deceleration method will lead to a longer time for shifting and speed regulation, resulting in a longer interruption of vehicle power, reducing the quality of shifting, and affecting the driving experience of the vehicle. SUMMARY OF THE INVENTION [0005] The present application provides a control method, device and medium for s...
