Embodiment Construction

[0025] figure 1 Shown is a schematic diagram of the device for controlling the starter motor 10 according to the invention. The device comprises an energy source 20 , a computing unit 30 and a control unit 40 of the starter motor 10 .

[0026] The control unit 40 serves to switch the starter motor 10 on or off by means of the control signal GD as a reaction to the control signal OC of the computing unit 30 . For this purpose, a control signal OC is applied to a control input 42 of a control unit 40 during operation of the device or is transmitted via a communication interface. A control signal GD for the starter motor 10 is provided at an output 45 and is connected, for example, to a control connection of a not shown controllable switching element of the starter motor 10 . The control unit 40 also comprises a first so-called disable input 41 , a reset input 43 and a second disable input 44 . During operation of the device, if an undervoltage is detected or an error is detec...

Abstract

The invention relates to a method for driving a starter motor (10) of a vehicle. Upon receipt or following receipt of a reset signal (NRES), a control unit (40) of the starter motor (10) checks the state a switch-off signal (DIS, DIS_L; NDIS, NDIS_L) prior to or in time with the receipt of the reset signal (NRES). The control unit (40) switches on or off the starter motor (10) according to the response of a computing unit (30) to a control signal (OC, OC_L). The switch-off signal (DIS, DIS_L; NDIS, NDIS_L) is generated by a monitoring unit (22) monitoring the computing unit (30) or the monitoring unit (33) in the computing unit (30), and the control unit (40) is supplied via a dedicated line. Depending on the result of the review, the presence of an undervoltage or an error is concluded.

Description

technical field [0001] The invention relates to a method and a device for controlling a starter motor of a motor vehicle. Background technique [0002] So-called start-stop systems are used in modern motor vehicles, whereby the internal combustion engine of the motor vehicle is switched off during the parking phase, for example at a stop light. For example, the clutch pedal is actuated, or the brake pedal is activated in vehicles with an automatic transmission, so that the internal combustion engine can be switched on again by means of the starter motor. Actuating the starter motor often leads to disturbances in the supply voltage of the vehicle's on-board electrical system. The voltage at this time may be lower than a predetermined limit value (the so-called lower voltage limit value) in some cases, so a so-called brown-out reset is carried out. [0003] During brown-out reset, the car controller including the controller of the starter motor is reset. However, in order t...
