• a first failsafe, comprising a signal receiver for receiving a second indicator signal from the second electric vehicle motor controller, wherein the first failsafe is configured to enable activation of the first power provider based on the received second indicator signal;
• and
• a first processor, wherein the first processor is arranged to control operation of the first power provider based on the second indicator signal received from the second electric vehicle motor controller,
• and wherein the second electric vehicle motor controller comprises:
• a second power provider;
• a second health indicator configured to provide a second indicator signal only in the event that operation of the first electric vehicle motor controller is consistent with safe operation of the vehicle, and to check said safe operation by comparing a drive direction of the first electric vehicle motor controller with information obtained from the CANBUS of the vehicle;
• a second failsafe, comprising a signal receiver for receiving the first indicator signal from the first electric vehicle motor controller, wherein the second failsafe is configured to enable activation of the second power provider based on the received first indicator signal;
• and
• a second processor, wherein the second processor is arranged to control operation of the second power provider based on the first indicator signal received from the first electric vehicle motor controller.
