Abstract
A system and method for controlling air conditioning and ISG systems for a vehicle are provided. The system includes a heater controller that detects a defrost mode selection signal or an A/C blower operation signal and transmits the signal to a cluster controller. The cluster controller then transmits the defrost mode selection signal or the A/C blower operation signal to an engine ECU. The engine ECU determines ISG entry prevention or ISG release after ISG entry in response to receiving the defrost mode selection signal or the A/C blower operation signal from the cluster controller.
Claims8
A system for controlling air conditioning and idle stop and go (ISG) systems for a vehicle, comprising:
- a heater controller configured to detect a defrost mode selection signal or an air conditioner (A/C) blower operation signal, and transmit the defrost mode selection signal or the A/C blower operation signal to a cluster controller, the cluster controller being connected to the heater controller by a direct connection in a pin-to-pin manner;
- the cluster controller configured to receive the defrost mode selection signal or the A/C blower operation signal from the heater controller via the direct connection;
- and
- an engine electronic control unit (ECU) configured to receive the defrost mode selection signal or the A/C blower operation signal from the cluster controller via CAN communication, the engine ECU being communicably connected to the cluster controller through a controller area network (CAN) communication line and being connected to the heater controller in the pin-to-pin manner for signal transmission therebetween, and the engine ECU being configured to determine ISG entry prevention or ISG release after ISG entry.
A method of controlling air conditioning and idle stop and go (ISG) systems for a vehicle, comprising:
- receiving, by an engine electronic control unit (ECU), a defrost mode selection signal or an air conditioner (A/C) blower operation signal, received from a cluster controller via a heater controller, the cluster controller being connected to the heater controller by a direct connection in a pin-to-pin manner;
- and
- determining, by the engine ECU, ISG entry prevention or ISG release after ISG entry, the engine ECU being communicably connected to the cluster controller through a controller area network (CAN) communication line and being connected to the heater controller in the pin-to-pin manner for signal translation there-between.
