Description:FIELD OF THE INVENTION
[001] The present invention relates to a vehicle. More particularly, the present invention relates to a system for accessing a vehicle.

BACKGROUND OF THE INVENTION
[002] In recent years, the integration of wireless communication systems into vehicle control systems has become increasingly prevalent. One significant application of this technology is in remote keyless entry (RKE) systems, where wireless transmitters/receivers are utilized for functions such as locking/unlocking doors, trunk access, and activating alarm systems of the vehicle. These systems have evolved further to include Passive Entry and Passive Start (PEPS) systems, offering enhanced convenience and safety features for vehicle users.
[003] These systems typically involve a portable communication device, such as a key fob or card, which communicates with a module within the vehicle to perform various functions like door lock/unlock and engine start. One key aspect of these systems is the bidirectional communication between the vehicle's electronic control module (ECU) and the portable device. Upon receiving a request for action, the vehicle's transceiver broadcasts an interrogating signal, to which the portable communication device responds with an encrypted code, thus enabling the desired operation.
[004] However, existing keyless entry systems for automobiles face significant challenges, including issues related to data transmission efficiency and security. Additionally, remote keyless entry systems encounter data communication inefficiencies, particularly during the encryption process due to unforeseen circumstances. Further, the current keyless entry systems lack a comprehensive and secure ranging method that combines proximity detection with cryptographic challenge/response mechanisms. This leads to insufficient security measures and unauthorized access to vehicle systems, potentially leading to vehicle theft or unauthorized access. Despite the adoption of various authentication methods, reauthenticated communication remains a persistent problem in keyless entry systems. This leads to latency issues and the potential interruptions during the encryption process, results in compromised user experience and security vulnerabilities. Moreover, reauthentication leads excessive data consumed during communication, which not only impacts system efficiency but also contributes to higher power consumption over time resulting in reduced battery life and increased operational costs for vehicle owners.
[005] In view of the foregoing, it is desirable to overcome a least the above-mentioned disadvantages of the prior art.

However, these examples should not be construed as limiting as different variations of the encrypted unique identification number can be defined by the manufacturer of the vehicle.
[041] The method further comprises step 208 of authenticating the first user input based on the first response received from the first control unit 122. The step 206 of authenticating is performed by the second control unit 130. In an example, the first response is processed to authenticate such that the second control unit 130 determines if the first response matches the expected encrypted unique identification number.
[042] The method further comprises step 210 of executing the command indicative of the first user input based on the authentication. The step 210 of executing is performed by the second control unit 130.
[043] The method further comprises step 212 of transmitting a second encrypted unique identification number to the first control unit 122 without receipt of a command indicative of a second user input from the first control unit 122. The step 212 of transmitting is performed by the second control unit 130.

Thereby, the present invention reduces the number of connections between the second control unit 130 of the vehicle 132 and first control unit 122 of the portable electronic device 120, and therefore decreases the boot-up time of the vehicle 132, data and power consumed.
[044] The method further comprises a step 214 of receiving a second response to the second encrypted unique identification number from the first control unit 122. The step 214 of receiving is performed by the second control unit 130.
[045] The method further comprises step 216 of executing the command indicative of the second user input without authentication of the second response. The step 216 of executing is performed by the second control unit 130. For example, the second control unit 130 of the vehicle 132 transmits another encrypted identification number as part of the communication signal to the first control unit 122 of the portable communication unit 120. Upon receiving a signal from the first control unit 122 in response, the second control unit 130 sends a signal to execute the command indicative of the second user input without authentication. Thereby, the present invention eliminates the need for reauthentication between the portable electronic device 120 and the vehicle 132 reducing signal latency which otherwise exist in conventional keyless entry system. Further, the present invention reduces data and power consumption.
[046] Figure 4 illustrates a flow diagram of a method for accessing a vehicle, in accordance with an embodiment of the present invention.

At step 304, a first user input is received from the user on the portable electronic device 120. The first control unit 122 is configured to transmit a command indicative of a first user input to the vehicle control unit 130. At step 306, if the command indicative of the first user input is received for the first time, the step moves to 308. At step 308, the vehicle control unit 130 transmits a first encrypted unique identification number. At step 310, the first control unit 122 of the portable electronic device 120 receives the first encrypted unique identification number and computes a first response. Upon receiving the first response and authenticating the first response, at step 312, the vehicle control unit 130 executes the command indicative of the first user input. At step 306, if the command indicative of the first user input is not received for the first time, the step moves to 314. At step 314, the vehicle control unit 130 transmits a second encrypted unique identification number in advance for the next session in the same session. At step 316, the first control unit 122 of the portable electronic device 120 receives the second encrypted unique identification number and computes a second response in advance. Upon receiving the second response, at step 318, the vehicle control unit 130 executes the command indicative of the second user input without authentication.
