Abstract

The present subject matter discloses an automated load detection system (ALDS) (110) and a sensor assembly (104) may be communicatively coupled to the tyre (102). The ALDS (110) may receive location data (132) of the sensor assembly (104) and it may ascertain presence of the sensor assembly (104) in a contact patch of the tyre (102). The sensor assembly (104) may share sensor data (134) with the ALDS (110). The ALDS (110) may generate an acceleration profile based on vehicle parameter (136) received from the vehicle (101) along with the sensor data (134). The ALDS (110) may determine a contact patch length (CPL) based on the acceleration profile and a loaded radius of the tyre (102) based on the CPL.
