The invention discloses a multi-mode multi-target coordination control method for a distributed drive-by-wire chassis electric vehicle, which realizes multi-mode multi-target coordination control, reduces the energy consumption and tire wear of the vehicle at a low speed, improves the operation performance and response performance of the vehicle under a high-speed conventional working condition, and improves the safety of the vehicle. And the safety and stability of the vehicle under the high-speed limit working condition are improved. Comprising the following steps: step 1, based on a current vehicle state and an observed road adhesion coefficient, carrying out classification and identification on a vehicle operation mode in a low-speed working condition, a high-speed conventional working condition and a high-speed limiting working condition based on a rule; 2, low-speed working condition multi-target coordination control is carried out; 3, high-speed conventional working condition multi-target coordination control is carried out; 4, high-speed limit working condition multi-target coordination control is carried out; and 5, controlling the transition process of each working condition.
