AUTOMOBILE ELECTRONIC PARKING EXECUTION CONTROLLER WITH DOUBLE-MCU REDUNDANCY DESIGN
An automobile electronic parking execution controller with a double-MCU redundancy design comprises a parking switch circuit, a biaxial acceleration sensor unit, a main micro control unit (MCU) U2 and a monitoring MCU U1, wherein the main MCU U2 controls a parking motor by means of detecting signals of the parking switch circuit and the biaxial acceleration sensor, the monitoring MCU U1 monitors a running state of a whole control system and restores the main MCU U2 when the main MCU U2 is abnormal, and the main MCU U2 restores the monitoring MCU U1 when the monitoring MCU U1 is abnormal. After the main MCU U2 crashes, the main MCU U2 can still be quickly stored through the monitoring MCU U1, so that the main MCU U2 quickly enters a response state to recover the parking brake control ability, which improves the safety of the system.

CONTROLLER AND CONTROL METHOD
The present invention obtains a controller and a control method capable of appropriately emitting an emergency braking signal in a straddle-type vehicle.
A controller (60) and the control method according to the present invention control operation of a straddle-type vehicle (100) in which anti-lock brake control for a front wheel (3) and anti-lock brake control for a rear wheel (4) are executed. An acquisition section of the controller (60) acquires an anti-lock brake actuation state showing whether the anti-lock brake control is actuated for any of the wheels (3, 4). A determination section of the controller (60) determines a threshold value on the basis of the anti-lock brake actuation state. An output section of the controller (60) outputs an emergency braking signal command in the case where deceleration of the straddle-type vehicle (100) is higher than the threshold value.
METHOD FOR DETECTING A BRAKING ACTION OF A RAILWAY VEHICLE AND EMERGENCY BRAKING METHOD OF A RAILWAY VEHICLE
A method is described for detecting a braking action of a railway vehicle (RV) comprising monitoring the load transfer to a first axle of the railway vehicle (RV) from a second axle following the first axle according to the direction of travel (d) and, if the load transfer exceeds a predetermined threshold, determining that the railway vehicle (RV) is braking. An emergency braking method is also described comprising detecting an emergency braking request, activating an electrodynamic braking system to decelerate the railway vehicle when the emergency braking request is detected, applying the method to detect a braking action of a railway vehicle and, if so, determining that the electrodynamic braking system is operating correctly and using the electrodynamic braking system to fulfill at least partially the emergency braking request.
