Abstract: A vehicle control system for a vehicle may include a radio frequency (RF) assembly including an RF assembly housing to be positioned within the vehicle, an antenna carried by the RF assembly housing, an RF receiver carried by the RF assembly housing, and a motion sensor carried by the RF assembly housing. The system may further include a controller assembly including a controller assembly housing to be positioned within the vehicle spaced apart from the RF assembly, and a controller carried by the controller housing. The controller may perform at least one first operation responsive to RF signals received by the RF receiver from a remote transmitter, and perform at least one second operation responsive to the motion sensor.

Abstract: A remote start system is for a vehicle including an ignition switch sequentially movable to a plurality of switch positions, and a plurality of ignition switch wires coupled to the ignition switch. The remote start system may include a wiring harness having a plurality of remote start wires to be arbitrarily coupled to the plurality of ignition wires, a wireless receiver responsive to a wireless remote start signal, and a controller coupled to the wiring harness and the wireless receiver. The controller may, in a learning mode, perform a mapping of the remote start wires to the ignition wires based upon sequential movement of the ignition switch to the plurality of switch positions. The controller may, in an operating mode, selectively activate the remote start wires based upon the mapping to remote start an engine of the vehicle responsive to the wireless receiver.

Abstract: A vehicle security system may include a vehicle controller and a first wireless communications device coupled thereto, and at least one wireless sensor. The wireless sensor may include a housing having a threaded mounting surface, a motion sensor carried by the housing, a second wireless communications device carried by the housing, and a sensor controller carried by the housing. The sensor controller is configured to determine when motion of the housing exceeds a first threshold, and send a first security alert message to the vehicle controller based thereon via the second and first wireless communications devices, and determine when the first threshold is exceeded for a predetermined time and enter a power saving mode based thereon. The at least one sensor may also include a power source carried by the housing to power the motion sensor, second wireless communications device, and sensor controller.

Abstract: A vehicle security system may include a vehicle controller and a first wireless communications device carried by the vehicle, and a wireless security sensor(s). The wireless security sensor(s) may include a portable housing, a motion sensor carried by the portable housing to detect motion thereof, a second wireless communications device carried by the portable housing to communicate with the first wireless communications device, and a sensor controller carried by the portable housing. The sensor controller may cooperate with the motion sensor and the second wireless communications device to determine when motion of the portable housing exceeds a first security alert threshold and send a first security alert message to the vehicle controller based thereon, and determine when the first security alert threshold is exceeded for a predetermined time and enter a power saving mode. The vehicle controller may generate a first alarm responsive to the first security alert message.
