A system configured for operation below a threshold temperature system includes a power supply, a housing, a temperature-sensitive electronic component, and a heating circuit. The temperature-sensitive electronic component is enclosed within said housing and electrically connected to the power supply, wherein the temperature-sensitive electronic component becomes susceptible to failure when the temperature of said temperature-sensitive electronic component decreases and crosses the threshold temperature. The heating circuit is at least partially enclosed within the housing and comprising a temperature-dependent resistor, the heating circuit electrically connected to the power supply and configured to generate heat energy within the housing when the temperature within the housing decreases and approaches the threshold temperature in order to maintain the temperature of the temperature-sensitive electronic component above the threshold temperature.

The present invention relates to a method for detecting overheating of an electrical heating device comprising a plurality of resistive elements configured to be supplied electrically using a control signal by pulse width modulation according to a setpoint, comprising the following steps:—detecting the setpoint,—detecting the duty cycle (PWM_system; PWM_subsystem),—defining a threshold value for detecting the duty cycle according to the setpoint, or a value of at least one parameter for monitoring an incidence of overheating—comparing the detected duty cycle value with the detection threshold value, and—detecting an incidence of overheating when the detected duty cycle value reaches the detection threshold value. The invention also relates to a corresponding control unit.

A heating system for a vehicle wing element, wherein the wing element is moveably arranged between an open position and a closed position relative to a vehicle main structure. The heating system includes a heating element at a contact surface between the wing element and the main structure and a control unit for activating the heating element. The system further includes a wing element handle sensor and a wing element latch switch. The switch is operatively connected to the control unit for sending a signal indicative of its state to the control unit. The control unit is arranged to send an activation signal to the heating element when the control unit receives a signal from the wing element handle sensor that the handle is being pulled and a signal from the wing element latch switch that the wing element is closed.

A vehicle including a rear bumper having an upper surface, a power source, and a heating element in communication with the power source is provided. The heating element extends in a vehicle lateral direction and along substantially an entire portion of the upper surface of the rear bumper. The heating element may operable when a tailgate is in a closed position. Thus, debris, such as ice, dirt, and the like, accumulating on the upper surface of the rear bumper may be melted by the heating element prior to the tailgate opening. The heating element may be configured to heat substantially an entire portion of the upper surface of the rear bumper. The heating element may be configured to heat upon a condition being satisfied such as, for example, a vehicle start operation or outside temperature being below a predetermined threshold.

A heater device includes a heat generating part that generates heat by energization, and a detection unit. The detection unit detects whether or not a distance between an object around the heat generating part and the heat generating part is equal to or less than a first detection distance with a first detection sensitivity, and whether or not the distance between the object around the heat generating part and the heat generating part is equal to or less than a second detection distance shorter than the first detection distance with a second detection sensitivity that is less sensitive than the first detection sensitivity.

An electric heating device includes an electric control device with a control housing that is in structural unity with a housing of a power section. The power section has a frame forming a heating chamber. At least one PTC heating device with at least one PTC element and conductor elements is provided in the heating chamber. The control housing forms a chamber which is separated from the frame by a partition wall. A heat sink projects from the partition wall into the power section. The electric control device has a printed circuit board and at least one power switch which generates a power loss and which is connected in a heat-conducting manner to a surface of a heat sink. An electrically insulating layer and a spring element, which holds the power switch applied under pretension against the surface of the heat sink, are provided between the power switch and the heat sink.

A transmission for a motor vehicle, including a housing, which at least partly encloses at least one movable transmission part and is filled with an operating medium during a normal operation of the transmission, and including a heating element which dispenses a heat output in order to heat the operating medium. One object is to increase a coupling surface for dispensing a heat output to the operating medium in a simple manner. The heating element is designed to dispense the heat output to the housing via a first coupling surface, and the housing is designed to dispense the heat output to the operating medium via a second coupling surface. The heat output can be transmitted from the heating element to the operating medium in a significantly indirect manner via the housing.
