Abstract

A method for remote start control of a hydrogen fuel cell vehicle includes receiving a remote start command via a wireless communication network, transmitting a start signal corresponding to the remote start command through an in-vehicle network, transmitting a start mode in response to the start signal, determining a response waiting time corresponding to the start mode, receiving an operation result of the start signal through the in-vehicle network during the response waiting time, and transmitting the operation result over the wireless communication network.

First claim

What is claimed is:

1 . A method for remote start control of a hydrogen fuel cell vehicle, the method comprising steps of:
receiving, by a telematics terminal, a remote start command via a wireless communication network; transmitting, by the telematics terminal, a start signal corresponding to the remote start command through an in-vehicle network; transmitting, by a vehicle controller, a start mode in response to the start signal; determining, by the telematics terminal, a response waiting time corresponding to the start mode; receiving, by the telematics terminal, an operation result of the start signal through the in-vehicle network during the response waiting time; and transmitting, by the telematics terminal, the operation result over the wireless communication network.

2 . The method according to claim 1 , wherein the start mode includes a normal start mode and a cold start mode, and
in the cold start mode, an in-vehicle motor is driven under a condition that a temperature in a fuel cell of in the hydrogen fuel cell vehicle is equal to or lower than a predetermined temperature, and in the normal startup mode, the in-vehicle motor is driven under a condition that the temperature in the fuel cell exceeds the predetermined temperature.

3 . The method according to claim 2 , wherein the predetermined temperature is 30 degrees below zero Celsius (° C.).

4 . The method according to claim 2 , wherein the response waiting time in the normal startup mode is 30 seconds, while the response waiting time in the cold start mode is one minute.

5 . The method according to claim 1 , wherein the start signal is transmitted at least twice in a predetermined cycle during the response waiting time.

6 . The method according to claim 5 , wherein the predetermined cycle is ranged in 10 seconds to 20 seconds.

7 . The method according to claim 5 , further comprising:
determining delivery cycle of the start signal according to the start mode.

8 . The method according to claim 1 , wherein a preparation time for driving a motor equipped in a vehicle differs according to the start mode.

9 . The method according to claim 1 , wherein the remote start command is transmitted from a telematics server coupled through the wireless communication network.

10 . The method according to claim 1 , wherein the start signal is transmitted from the telematics terminal into a vehicle controller through a controller area network (CAN), and the start mode is transmitted from the vehicle controller into the telematics terminal via the controller area network (CAN).

11 . An apparatus for remote start control of a hydrogen fuel cell vehicle engaged with a mobile device or a network server, comprising a processing system that comprises at least one data processor and at least one computer-readable memory storing a computer program, wherein the processing system is configured to cause the apparatus to:
receive remote start command via a wireless communication network; transmit a start signal corresponding to the remote start command through an in-vehicle network; transmit a start mode in response to the start signal; determine a response waiting time corresponding to the start mode; receive an operation result of the start signal through the in-vehicle network during the response waiting time; and transmit the operation result over the wireless communication network.

12 . An apparatus for remote control of a hydrogen fuel cell vehicle, the apparatus comprising:
a telematics terminal for receiving a remote start command via a wireless communication network and transmitting a start signal corresponding to the remote start command through an in-vehicle network; and a vehicle controller for transmitting a start mode to the telematics terminal in response to the start signal, wherein the telematics terminal is further determines a response waiting time corresponding to the start mode, receives an operating result of the start signal through the in-vehicle network during the response waiting time, and transmits the operation result over the wireless communication network.

13 . The apparatus according to claim 12 , wherein the start mode includes a normal start mode and a cold start mode, and
in the cold start mode, an in-vehicle motor is driven under a condition that a temperature in a fuel cell of the hydrogen fuel cell vehicle is equal to or lower than a predetermined temperature, and in the normal startup mode, the in-vehicle motor is driven under a condition that the temperature in the fuel cell exceeds the predetermined temperature.

14 . The apparatus according to claim 13 , wherein the predetermined temperature is 30 degrees below zero Celsius (° C.).

15 . The apparatus according to claim 13 , wherein the response waiting time in the normal startup mode is 30 seconds, while the response waiting time in the cold start mode is one minute.

16 . The apparatus according to claim 12 , wherein the start signal is transmitted at least twice in a predetermined cycle during the response waiting time.

17 . The apparatus according to claim 16 , wherein the predetermined cycle is ranged in 10 seconds to 20 seconds.

18 . The apparatus according to claim 16 , wherein the telematics terminal determines a delivery cycle of the start signal according to the start mode.

19 . The apparatus according claim 12 , wherein a preparation time for driving a motor equipped in a vehicle differs according to the start mode.

20 . The apparatus according to claim 12 , wherein the start signal and the start mode are delivered via a Controller Area Network (CAN).
