Problems solved by technology

In conventional systems this alternator output changes too quickly for the ECU to react
Since the time constant of the engine is larger than that of the alternator, the throttle control cannot be adjusted in time, which affects the idle speed of the engine

Abstract

The invention discloses an automobile intelligent generator management system, comprising a voltage regulator and an ECU. The voltage regulator includes an MCU, a power module, a voltage sampling circuit, an excitation control circuit, an indicator light control circuit, a rotational speed sampling circuit and the ECU for communication Control circuit; MCU leads out the B+ terminal through the voltage sampling circuit and is connected with the power generation output end of the generator; MCU leads out the P terminal through the rotational speed sampling circuit and is connected with the phase output end of the generator; MCU leads the excitation control terminal F through the excitation control circuit and It is connected to one end of the generator excitation coil; the MCU leads the L end through the indicator light control circuit, and the L end is connected in series with the charging indicator light and the ignition switch, and then connected to the B+ end in parallel with the positive electrode of the battery; the MCU is bidirectionally connected to the ECU through the ECU communication control circuit. The management system enables the ECU to dynamically control the generator output according to the real-time load condition, and can improve the stability of the alternator under the engine idle state, thereby improving the fuel consumption of the vehicle.

Description

technical field [0001] The invention relates to an automobile generator management system, in particular to an automobile intelligent generator management system. Background technique [0002] In the automotive alternator system, the voltage regulator realizes the automatic adjustment of the output voltage of the generator by controlling the excitation current of the generator. Existing voltage regulators include single-function and multi-function regulators. The conventional terminals of a single-function voltage regulator are: B+ terminal - connected to the voltage output terminal of the generator, F terminal - connected to the excitation coil, E terminal - ground terminal, S terminal - connected to the positive pole of the battery for detection Measure the voltage of the battery, C terminal - used to reduce the output of the generator to reduce the engine load, L terminal - the battery indicator light, IG terminal - connected to the ignition switch on the car, FR termina...
