But the disadvantage is that this not only increases the weight of the engine, but also increases the cost, fuel consumption, emissions, etc. of the engine. At the same time, the precise control of the clutch also requires higher requirements and greater difficulty.
In addition, if the vehicle load is heavy, the clutch itself will be worn out and the service life of the clutch will be shortened.

The invention belongs to the technical field of new energy vehicle control, and particularly relates to a control method for limping to home of a hybrid vehicle and the hybrid vehicle. The control method is used when a power battery breaks down in the vehicle travelling process and comprises the following steps that a whole vehicle controller sends a limping-to-home mode demand to a generator anda driving motor, the whole vehicle controller controls an engine to reach the calibrated rotating speed and keeps the engine rotate at the calibrated rotating speed, the generator generates the induction electromotive force with rotation of the engine, and the whole vehicle controller sends a torque demand instruction to the driving motor, the driving motor responds to the torque demand instruction and outputs the corresponding demand torque for driving the vehicle to start. By using the control method for limping to home of the hybrid vehicle and the hybrid vehicle, and on the basis that thecurrent output power of the engine is not changed, traffic jam caused by breakdown of the hybrid vehicle under the condition that the power battery capacity cannot be used can be effectively avoided.
Description
technical field [0001] The invention belongs to the technical field of new energy vehicle control, and in particular relates to a control method for a hybrid vehicle limp home and the hybrid vehicle. Background technique [0002] At present, there are more and more new energy buses on the market. Compared with traditional vehicles, the difference in structure is that the rear end of the engine of the new energy bus is equipped with a shock absorber and an ISG generator, and the gearbox is canceled at the rear end of the clutch. The TM drive motor is added, and the power battery is also added. Under normal circumstances, the TM drive motor is powered by the power battery to drive, but when the bus vehicle is operating normally in the market, but the power battery fails due to serious failure, the vehicle will break down and cause traffic jams. [0003] If the power battery of the existing vehicle cannot be used, it needs to use the pure engine mode to run, that is, after the...
