A vehicle including a front module including a front wheel and a rear module selectively moveably connected to the front module, the rear module including a rear wheel. The vehicle further includes an electric motor assembly, a mode selector, at least one extension assembly connected between the front module and the rear module for selectively extending and retracting to provide a selective variation in an overall length of the vehicle; and a vehicle control unit being communicatively connected between the mode selector and the electric motor assembly. The vehicle control unit performs a method for selectively changing the overall vehicle length. The method includes receiving from the mode selector an indication to change the overall length, determining that the front wheel is rotationally locked, and causing an electric motor to drive the rear wheel such that the rear module translates relative to the front module.

A drive assistance device (24) for a saddle type vehicle (1) includes a ride sensor (37) configured to detect a ride attitude of a rider (J), a vehicle body behavior generating part (25) configured to generate a behavior on a vehicle body by a prescribed output, and a controller (27) configured to control driving of a plurality of devices (BR, EN, ST) included in the vehicle body behavior generating part (25), and, when at least one of the plurality of devices (BR, EN, ST) is actuated regardless of the operation of the rider (J), the controller (27) determines which of the plurality of devices (BR, EN, ST) is to be actuated according to the ride attitude of the rider (J) detected by the ride sensor (37).

One variation of a system includes: a cam block mounted to a deck of a scooter and defining cam lobes arranged about a pivot feature and cam heels between the set of cam lobes; a pivot block pivotably coupled to the pivot feature and defining followers riding over the cam lobes; a pair of wheel uprights locating a pair of wheel assemblies; a first lateral link extending between and coupled to the pair of wheel uprights and pivotably coupled to the pivot block; a second lateral link extending between and coupled to the pair of wheel uprights, vertically offset from the first lateral link, and coupled to the pivot block between pair of wheel uprights; and a spring element driving the followers of the pivot block into cam heels to bias the second lateral link toward a neutral position.

A method for carrying out autonomous braking in a two-wheeled motor vehicle, where the necessity of vehicle deceleration is detected with the aid of a surround sensor system. When vehicle deceleration is necessary, prior to its execution, a test braking action independent of a rider and of a predefined temporal length is carried out. During or after the execution of the test braking action, a rider readiness variable characterizing the readiness of the rider to master the vehicle deceleration detected as necessary is ascertained. After completion of the test braking action, the vehicle deceleration is initiated, the time characteristic of the vehicle deceleration being a function of the rider readiness variable.

A braking apparatus for stopping a children's kick scooter is described. The braking apparatus comprises a hand-held remote control to transmit a command signal when a radio-frequency (RF) signal transmitter is activated. The braking apparatus also comprises a remote control signal receiver located on the children's kick scooter to receive the command signal and convert it to an electric current. The braking apparatus additionally comprises a linear actuator to receive the electric current. The linear actuator comprises a linear actuator electric motor and a linear actuator shaft. The linear actuator electric motor is activated by the electric current and moves the linear actuator shaft from a first position to a second position. The braking apparatus further comprises a brake system to press a metal plate against a rear wheel of the children's kick scooter, thereby stopping the children's kick scooter when the linear actuator shaft is in the second position.
