AI Technical Summary
Technical Problem
Existing traction control systems make it difficult for drivers to detect and correct wheel slippage, and system intervention may lead to irregular operation of the internal combustion engine and mechanical damage.
Method used
The twin control unit independently controls the fuel injection of the internal combustion engine, and provides feedback to the driver by generating abnormal vibrations and noise through periodic pulse deviation events, while avoiding damage to the internal combustion engine and catalytic converter.
Benefits of technology
It effectively alerts the driver to drive wheel slippage, improves the interaction between the driver and the vehicle, and avoids irregular operation of the internal combustion engine and mechanical damage.

Abstract
本发明涉及一种在驱动轮(3)打滑期间控制道路车辆(1)的控制方法，驱动轮由内燃机(4)引起旋转，内燃机具有布置成两排(10)的多个气缸(11)，并具有分别将燃料喷射到对应的气缸中的多个燃料喷射器(16)。控制方法包括以下步骤：检测至少一个驱动轮的打滑；以及仅在至少一个驱动轮打滑期间，用信号规则控制内燃机，该信号规则使内燃机以异常方式工作，从而产生能被驾驶员感知到的异常振动和 / 或异常噪声。内燃机具有两个孪生的控制单元(18)，其中每个控制单元与对应的排(10)相关联，控制其自己的排(10)的所有且单独的喷射器并相对于另一个控制单元完全独立且自主地启动信号规则。
