Abstract
Method and apparatus are disclosed for mobile device relay attack detection and power management for vehicles. An example vehicle includes a first module for first protocol communication, a second module for second protocol communication, and a controller. The controller is to determine a first distance to a mobile device utilizing a signal strength of the first protocol communication and determine, upon receiving an entry request, a second distance to the mobile device utilizing a time-of-flight of the second protocol communication. The controller also is to prevent entry when the second distance does not match the first distance.
