An electric racing power system for F1 driver training

technical field

The utility model relates to an electric racing car power system for F1 driver training, which belongs to the innovative technology of the electric racing car power system for F1 driver training.

Background technique

At present, the process of cultivating and training F1 drivers is generally from computer simulation → real car training. Computer simulation training is for students to initially master the basic skills of driving. The cost is low, but it lacks real driving experience, and it is difficult to improve the driver's real car driving skills. When directly switching from simulated driving to real car driving, it will cause the driver to be unable to adapt for a while, increase the tension and psychological burden of the driver, affect the driving level, and prolong the training time. Real car training is very expensive and will increase unnecessary training costs. Sometimes novice riders misuse due to nervousness, resulting in dangerous accidents. In response to this problem, Guangdong University of Technology previously proposed an energy-saving and environmentally friendly electric racing car for F1 driver training (ZL201320865666.4). The electric racing car for training is driven by a single motor. During the actual use, it was found that the power of the car is still lacking. It is very limited, so it is obviously not feasible to improve the power of the training car just by switching to a higher-performance drive motor. In order to improve the dynamic performance of training racing cars in a limited space arrangement, a new electric racing car power system for F1 driver training must be proposed.
