However, it should be noted that, in this way, the adjustment mode of energy recovery intensity level + accurate accelerator operation may have a high requirement on the driver skill level, which may increase the labor intensity of the driver to a certain extent, and in addition, many drivers may operate the brake pedal to adjust the vehicle deceleration by reducing the level of coasting energy recovery intensity, so as to reduce the operation difficulty and improve the vehicle smoothness.
In some embodiments, the deceleration trim switch module 101 includes one or more of: a key, a lever, or a knob. Thus, the driver can more conveniently adjust the deceleration of the vehicle by a key, a lever, or a knob mounted on the steering wheel.
In some embodiments, deceleration trim switch module 101 includes a positive trim switch assembly (+) and a negative trim switch assembly (-) with the positive trim switch assembly being operable by the driver to generate a positive trim signal for fine-tuning the rising energy recovery deceleration and the negative trim switch assembly being operable by the driver to generate a negative trim signal for fine-tuning the falling energy recovery deceleration, e.g., the electronic control unit may be based on the positive trim signal or the negative trim signalThe signal correspondingly ramps up and down the vehicle deceleration. More preferably, the electronic control unit 102 is further configured to adjust the energy recovery deceleration to exceed the energy recovery deceleration range according to the positive or negative trimming signal, for example, the energy recovery deceleration range corresponding to the current energy recovery level is 0-1m/s2But fine tuning by a fine tuning signal allows the vehicle deceleration to be adjusted to 0-2m/s2。

In the embodiment of the utility model, the deceleration fine setting switch module is added, and the two switches are divided into +, -switch. The controller needs to judge the on-off states of the two switches and identify long-press and short-press actions. Once the +/-switch is pressed for a short time, the coasting recovery deceleration is increased/decreased by 0.1m/s2 (calibratable) within 1s time (calibratable); +/-switch long on time, coast recovery deceleration increases/decreases at a rate of 0.3m/s2 (calibratable) per second.
