An assembly for an engine includes a control module including a controller operable to control at least certain aspects of the operation of the engine, a display including an input connected to the controller, and a wireless receiver connected to the controller. The wireless receiver is arranged to receive a signal from a wireless device to cause the controller to send an engine start signal to cause starting of the engine and wherein the input when actuated causes the controller to send an engine start signal to cause starting of the engine. In at least some implementations, no keyed ignition switch is provided to start the engine and the engine is started only via the wireless device or the input.

Methods and apparatuses for connecting multiple loads with a common return pin in engine control module application are disclosed. Only one of the multiple loads can be connected to a power source at a time. At the high side, each load is coupled to the power source through a respective pin at a connector. At the low side, the multiple loads share a common return pin at the connector that connects the loads to the ground. When a first load is connected to the power source at the high side, a first low side driver circuit is used to connect the first load to the ground at the low side. When a second load is connected to the power source at the high side, the second low side driver circuit is used to connect the second load to the ground at the low side.

A turbocharger assembly (1) comprises a turbine (4), a compressor (6), a housing (8), one or more electronic components (38, 40, 41, 42, 45, 47, 50, 51, 52, 54, 58) and a pettier device (46). The pettier device (46) is configured to provide electrical power to the one or more electronic components (38, 40, 41, 42, 45, 47, 50, 51, 52, 54, 58).

An engine control system for an internal combustion engine may include at least one energy harvesting module with at least one energy converter and at least one energy module for transmitting electric energy, and at least one sensor for detecting a physical or chemical measurement quantity on or in an engine component. The engine control system may also include a microcontroller connected to the sensor and the radio module and for processing the measurement quantity, a radio module for a wireless transmission of the measurement quantity to a radio receiver, and an engine control unit connected to the radio receiver and configured to evaluate incoming measurement quantities from the radio module, process the incoming measurement quantities into control signals, and transmit the control signals to the internal combustion engine for protecting the engine component. The energy module may be connected at least to the microcontroller and the radio module.

A power supply apparatus configures an on-board power supply system that includes a first battery and a second battery. A first module and a first detecting unit are electrically connected to the first battery as a first electrical load. A second module and a second detecting unit are electrically connected to the second battery as a second electrical load. The first module and the second module configure an electric power steering apparatus. A starter is electrically connected to the first battery. The first battery and the second battery are electrically connected by a connection path. A resistor unit is provided on the connection path.

A device and a method for checking switch-off paths in control units of internal combustion engines during ongoing engine operation.

A hybrid vehicle may include an engine controller that determines an activation state of an oxygen sensor when the engine controller is requested to operate an engine and controls a voltage applied to the oxygen sensor depending on whether or not the oxygen sensor is in an activated state, and a vehicle controller that controls a voltage of a battery of the hybrid vehicle and applies the voltage of the battery to the engine controller. The engine controller outputs an activation demand signal for the oxygen sensor to be activated to the vehicle controller when it is determined that the oxygen sensor is not in the activated state.
