Description

Vehicle access control system and method Technical Field The present disclosure relates to systems and methods for controlling access to a vehicle. Background Conventional vehicle access systems and methods typically use communication technologies such as Bluetooth Low Energy (BLE) and Ultra Wideband (UWB) communications and protocols, and use one or more digital keys within an access device (e.g., a key fob, or other mobile device such as a cell phone) to provide access to the vehicle. Such systems and methods generally rely on a one-factor authentication process that is based on cryptographic verification of a digital key (or keys) stored in an access device. Some access devices may provide a second level of protection, for example, a user may have to activate or "unlock" the device. However, more and more access devices are configured to be in a normally open state in order to minimize inconvenience to the user when approaching the vehicle. Thus, unauthorized use of an access device (e.g., caused by theft of the device) may pose a security threat. In contrast, conventional two-factor authentication methods, which require the user to enter a Personal Identification Number (PIN), for example, may be undesirable in order to avoid inconvenience to the user. Disclosure of Invention According to a first aspect of the present disclosure there is provided a system for controlling access to a vehicle and comprising transceiver means configured to transmit signals to and receive signals from access means of a user to provide an indication that the user is within a first range of the system, a sensing system comprising a camera and configured to record movement of the user in response to the indication, and a processor coupled to the sensing system and configured to analyze the movement, determine from the movement whether the user is one of a set of known users, and authenticate the user in response to determining that the user is one of the set of known users. Such a system therefore provides access based on a combination of the digital key in the access device and the user's own properties or characteristics, in particular those related to the way the user moves. In one or more embodiments, the system additionally includes an access controller configured to provide access to the vehicle in response to the processor authenticating the user. In one or more embodiments, the system additionally includes an access controller configured to provide access to the vehicle in response to both receiving authentication of the access device and authenticating the user by the processor. Thus, the access device may implement mobile identification, or may implement identification and directly provide a second factor for authentication. The movement may include gait. Gait is a type of movement that is generally unique to a group of individuals, or very small individuals. Thus, using gait as "biometric identification" can uniquely identify an individual, or identify an individual with a high degree of confidence, and is particularly convenient because gait may be less dependent on environmental factors such as lighting than other biometric identifications such as facial identification. In one or more embodiments, the transceiver device includes a Bluetooth Low Energy (BLE) device configured to authenticate an access device. The access controller may include a lock and providing access includes unlocking the lock. Further, the access controller may include a vehicle management system, and providing access includes enabling the vehicle management system. In one or more embodiments, the processor is further configured to authenticate the user without determining whether the user is one of a set of known users in response to receiving the indication that the user is a guest user. Thus, the system may include a "bypass" function, for example, if the system does not have enough data about the possible users to authenticate the users with a high enough confidence. According to another aspect of the present disclosure, there is provided a method of controlling access to a vehicle, comprising receiving an indication that an access device of a user is within a first range of the vehicle, recording, by a sensing system comprising a camera, movement of the user in response to the indication, analyzing the movement, determining from the movement whether the user is one of a set of known users, and authenticating the user in response to determining that the user is one of the set of known users. In one or more embodiments, receiving an indication that the access device of the user is within a first range of the system includes scanning for the presence of the access device using the transceiver device and exchanging a key with the access device. In one or more embodiments, the method additionally includes authenticating the user in response to the processor, providing, by the access controller, access to the vehicle. In one or more embodiments
