Abstract
Cilj magistrskega dela je izdelava nadzorne enote za električno vozilo s sinhronskima in-wheel motorjema. Nadzorna enota omogoča komunikacijo med krmilnikoma motorjev, prikazuje informacije uporabniku, ima možnost priklopa dodatnih senzorjev v prihodnosti in omogoča povezljivost z zunanjimi napravami preko brezžičnih tehnologij. Nadzorna enota je prototip, namenjen vgradnji v armaturo prototipnega vozila, in se napaja iz avtomobilskega akumulatorja. Glavna naloga nadzorne enote je komunikacija med krmilnikoma motorjev, ki se tako stalno sinhronizirata med seboj in regulirata navor motorjev za zagotavljanje funkcije diferenciala. To nalogo opravlja mikrokrmilnik PIC32MZ, ki preko vodila RS-485 komunicira s krmilnikoma v avtomobilu. Hkrati te podatke pošilja vmesniku HMI LCD Nextion, ki uporabniku prikazuje želene podatke in mu omogoča vnos podatkov. Tako lahko uporabnik spreminja jezik prikaza in tudi različne parametre na krmilnikih. Iz mikrokrmilnika je speljanih več dodatnih digitalnih vhodov in izhodov za morebitni priklop zunanjih naprav ter več analognih vhodov za priklop dodatnih senzorjev. Prav tako je dodanih nekaj močnostnih izhodov za vklapljanje močnejših bremen. Z brezžičnim Bluetooth modulom RN-42 in WiFi modulom ATWINC1500 pa je omogočeno dodajanje brezžične komunikacije z zunanjimi napravami, če bi bilo to potrebno.

Title:Electric vehicle control unit
Abstract:
The aim of the presented Master's thesis is developing of an electric vehicle control unit for electric vehicle with two synchronous in-wheel motors. Control unit enables communication between motor controllers, displays information to the user, has possibility of connecting additional sensors in the future and enables connectivity to external devices with wireless technologies. The control unit is a prototype, intended to be installed into the vehicle's dashboard and is connected to the car battery for its power supply. Main task of the control unit is communication between motor controllers. They are synchronised and the motor torque is appropriately regulated to provide function of the differential. This is done with PIC32MZ microcontroller, which communicates with the motor controllers in the vehicle over the RS-485 bus. It also sends the information to the Nextion HMI, which displays the desired information to the user and enables him/her to enter various data. The user can change the display language and different parameters of the motor controllers. Multiple digital inputs and outputs as well as analogue inputs are added to the microcontroller for connecting additional external devices and sensors. The control unit also features additional power outputs for driving more powerfull loads. Wireless communication with external devices is enabled by RN-42 Bluetooth module and ATWINC1500 WiFi module.
