On October 12, according to the official website of the State Intellectual Property Office, Zhejiang Geely Holding Group Co., Ltd. applied for a new hybrid safety technology patent, which can prevent the hybrid vehicle from directly breaking down when the second motor fails and ensure that the vehicle can operate for a long time.
No stall when driving at high speed.

According to public information, most current hybrid cars use DHT/E-CVT hybrid special transmissions, which integrate a generator, drive motor and reduction gear set.
in theory, if the drive motor fails, the vehicle may suddenly stop while driving due to loss of power, especially on highways, which is extremely dangerous.
In response, Geely Automobile applied for a technical patent on controlling hybrid vehicles to avoid “stall” during high-speed driving.
Specifically, according to the patent abstract, embodiments of the present application provide a control method and device for a hybrid vehicle, a hybrid vehicle and a medium, and belong to the technical field of vehicle control.
The method comprises: obtaining current speed data of the hybrid vehicle.
and filtering target speed data from the current speed data.
The state of the second motor is detected to obtain the motor state.
and a preset fault state is filtered out from the motor state.
Based on the target speed data and the fault state, the engine and the first motor are controlled to drive the hybrid vehicle.
In general, this technology can filter out the preset fault state of the motor through multiple layers through current speed data.
If it is determined that the second motor is in a fault state, the engine and the first motor are controlled to drive the hybrid vehicle to prevent the vehicle from breaking down directly and reduce safety hazards.
It is reported that this technology will be intensively applied in Geely’s next-generation Raytheon super electric hybrid system.
The battery life at full fuel and battery life can exceed 2000 kilometers.
The lowest power-loss fuel consumption will enter the 2L era and will be officially released within the year.
