Abstract
An energy dynamic control method for the EPS with hybrid power supply and an energy dynamic control system. Control system collects real-time current of vehicle electric appliances except the steering motor and the super-capacitor and calculates target current of the steering motor according to real-time steering torque and vehicle speed, and determines state of the super-capacitor by comparing rated current of vehicle power supply and sum of the current of vehicle electric appliances and target current of the steering motor. When super-capacitor is in the charging state, charging current is dynamically regulated to make vehicle power supply work in optimal working range, and maximum charging current is limited based on SOC of the super-capacitor. When super-capacitor is in discharging state, discharging current is dynamically regulated to make vehicle power supply work in optimal working range, and maximum discharging current is limited based on SOC of super-capacitor.
