“…For simplicity, the electric field of a moving vehicle is treated as a single magnetic dipole model [ 25 ], which can be induced by a metal electrode and a charge sensor circuit with ultra-high input impedance [ 26 ]. Previous studies conducted by our group have shown the feasibility of the recognition of hand motion direction and rotor direction based on charge induction [ 27 , 28 ].…”

In this paper, based on the principle of charge induction, a new velocity measurement method is proposed. A moving target generates a low-frequency electric field, which can be induced with an electrode and detection frontend. Velocity measurements are achieved by placing two electrodes at a fixed distance to detect the characteristic times. Firstly, the electric field generated by the moving target is modeled, and the theoretical output of the detection frontend is obtained via a simulation of the target passing by a single electrode. Then, according to the theoretical output, the velocity measurement simulation results of double electrodes are given for various driving conditions, such as a single vehicle driving in a single lane, a single vehicle changing lanes, two vehicles driving close together, and a multiple-vehicle situation. Finally, the above driving conditions are experimentally verified in sunny weather, windy and rainy weather, and a night environment.
