Aspects of the invention are directed towards a system and method for safe decoupling of the external power supply from a vehicle. The technology described herein provides an indication or an alert to the user at an appropriate time and avoids the possible damage to the system. The system comprises an electrical port by which the refrigerator can be connected to an external AC mains supply via an electrical cable when the vehicle is in stationary state. The system further comprises a refrigerator main controller unit (RMU) for controlling the power delivered to the refrigerator in both stationary and driving states of the vehicle. There is a safety system installed for restricting the vehicle from being driven when the electrical port of the system is connected to the AC mains supply via the electrical cable and the refrigerator is powered by the AC mains supply.

Systems and methods for reducing a current speed of a vehicle that can operate on solar energy to increase solar energy collection. The system may include a photovoltaic (PV) panel configured to receive sunlight to drive an electric motor, a solar loading sensor configured to detect solar load, a global position system (GPS) sensor configured to detect vehicle location data, a speed sensor configured to detect vehicle speed, and an electronic control unit (ECU) connected to the electric motor, the solar loading sensor, the speed sensor, and the GPS sensor. The ECU may determine whether the vehicle is exposed to solar load greater than a predetermined threshold value and, if so, present a driver of the vehicle a minimum acceptable speed to select based on sensor data and a difference of solar energy collection between the minimum acceptable speed and the current speed.

An electric vehicle control system and a control method, an electric vehicle power-on method, an electric vehicle power-off method, and an electric vehicle charging method are disclosed in this application. The control system includes a domain, control unit controlling an electric vehicle, a current sampling unit sampling the current of a power battery and a motor of the electric vehicle and sending sampling signals to the domain control unit, and electrical device, driven by the power battery, sampling the current flowing through it and sending the sampling signals to the domain control unit. The domain control unit, according to the sampling signals sent by the electrical device and the current sampling unit, manages the power battery and controls a motor driver module and the electrical device. The structure of the control system and the control policy are simplified and the power-on and power-off time is shortened.

Various systems and methods associated with protecting a rider of an electric bicycle from hazards while riding their bicycle are described. In some embodiments, the systems and methods enhance the safety of the rider in response current detected conditions surrounding the rider, such as conditions associated with the route or path traveled by the rider, other vehicles within the route or path traveled by the rider, potential hazards within the route or path traveled by the rider, environmental conditions through which the rider is traveling, and so on.

A trailer can be configured to selectively provide powered wheels, energy recovery, and/or parasitic power source charging. A trailer-related trigger (drive activation trigger, an energy recovery trigger, or a parasitic charging trigger) can be detected. When a drive activation trigger is detected, one or more motors can be activated to power one or more wheels of the trailer, thereby providing extra pushing power. When an energy recovery trigger is detected, one or more power sources of the trailer can be charged by recovering energy from the trailer. When a parasitic charging trigger is detected, one or more power sources of the trailer can be charged using a portion of the power generated by a main vehicle operatively connected to the trailer.

A system for a vehicle operable in a user-controlled driving mode and an automatic driving mode includes a hand-operated control element and a contact sensor configured to detect whether a driver of the vehicle is holding the control element. The system further includes a controller to monitor an alertness of the driver while the vehicle is in the automatic driving mode depending on whether the driver is holding the control element and/or switch operation of the vehicle between the user-controlled driving mode and the automatic driving mode depending on whether the driver is holding the control element.

Methods and systems are disclosed for customizing an advanced driver assistance system (ADAS) of a vehicle. In one example, a system for an electric vehicle comprises a current sensor arranged on a power line coupling a battery of the electric vehicle with an inverter of the electric vehicle; a directional speed sensor arranged at a motor of the electric vehicle; and a high voltage direct current contactor arranged on the power line coupling the battery of the electric vehicle with the inverter, upstream of the current sensor, the high voltage direct current contactor configured to allow a current to flow from the battery to the inverter when the high voltage direct current contactor is in a closed position, and to not allow the current to flow when the high voltage direct current contactor is in an open position.
