Classification: CPC B | IPC B

Claim 10:
11. The motorised trolley of claim 6 further comprising:
an Inertial Measurement Unit (IMU) connected to the controller and service braking effort of the electromechanical service brakes and torque output of the drive motors are controlled to compensate for temporary changes in the load sensor signals according to the dynamics and orientation of the trolley measured by the IMU;
a mode-change switch connected to the controller whereby, after selection of a manual recharge mode via the mode-change switch, the controller performs regenerative braking by the drive motors when the trolley is pushed or pulled by the user to recharge the battery, and
a free-wheeling mode that prevents electromechanical braking of the wheels and wherein, after selection of a free-wheeling operation mode via the mode-change switch, the controller actuates the at least one electric actuator for releasing the auxiliary brake.
