Abstract
A method of braking for a vehicle with a multi-phase electric motor, said motor including at least one stator group including a first stator arrangement and a second stator arrangement, each arrangement including three coils, each arrangement connected to respective low side and/or high side circuitry, each low side and/or high side circuitry including respective low side switches and high side switches, said method including: for either of said second or first arrangements, i) setting any two of said switches in said low side circuitry to a closed state and the other switch in an open state, and setting all the switches in the high side to an open state; and/or ii) setting any two of said switches in said high side circuitry to a closed state and setting the other switch to an open state, and setting all the switches on the low side to an open state.
